Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492584, here are decompositions:

7 + 31492577 = 31492584
17 + 31492567 = 31492584
31 + 31492553 = 31492584
43 + 31492541 = 31492584
47 + 31492537 = 31492584
107 + 31492477 = 31492584
113 + 31492471 = 31492584
131 + 31492453 = 31492584

Showing the first eight; more decompositions exist.
