Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460646, here are decompositions:

37 + 31460609 = 31460646
97 + 31460549 = 31460646
109 + 31460537 = 31460646
137 + 31460509 = 31460646
149 + 31460497 = 31460646
163 + 31460483 = 31460646
233 + 31460413 = 31460646
277 + 31460369 = 31460646

Showing the first eight; more decompositions exist.
