Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492556, here are decompositions:

3 + 31492553 = 31492556
19 + 31492537 = 31492556
79 + 31492477 = 31492556
103 + 31492453 = 31492556
127 + 31492429 = 31492556
157 + 31492399 = 31492556
163 + 31492393 = 31492556
313 + 31492243 = 31492556

Showing the first eight; more decompositions exist.
