Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460498, here are decompositions:

7 + 31460491 = 31460498
67 + 31460431 = 31460498
151 + 31460347 = 31460498
331 + 31460167 = 31460498
499 + 31459999 = 31460498
607 + 31459891 = 31460498
691 + 31459807 = 31460498
739 + 31459759 = 31460498

Showing the first eight; more decompositions exist.
