Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991460, here are decompositions:

7 + 991453 = 991460
13 + 991447 = 991460
31 + 991429 = 991460
73 + 991387 = 991460
79 + 991381 = 991460
103 + 991357 = 991460
199 + 991261 = 991460
313 + 991147 = 991460

Showing the first eight; more decompositions exist.
