Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492536, here are decompositions:

7 + 31492529 = 31492536
43 + 31492493 = 31492536
59 + 31492477 = 31492536
83 + 31492453 = 31492536
107 + 31492429 = 31492536
113 + 31492423 = 31492536
137 + 31492399 = 31492536
167 + 31492369 = 31492536

Showing the first eight; more decompositions exist.
