Peter said:


    All of these sequence are about "integers expressible as the sum of 2
primes in 'n' different ways", where n is some small number. Eg:

A067189 (n = 1)
    4, 6, 7, 8, 9, 12, 13, 15, 19, 21, 25, 31, 33, 39, 43, 45, 49, 55, 61,
63, 69, 73, 75, 81, 85, 91, 99, 103, 105, 109, 111, 115, 129, 133, 139, 141,
151, 153, 159, 165, 169, 175, 181, 183, 193, 195, 199, 201, 213, 225, 229,
231, 235, 241, 243, 253, 259, 265, 271, 273, 279, 283, 285, 295, 309, 313,
315, 319, 333, 339, 349, 351, 355, 361, 369, 375, 381, 385, 391, 399, 403,
411, 421, 423, 433, 435, 441, 445, 451, 459, ...

either 5 and 8 should both be here, or neither should be
