Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492662, here are decompositions:

11 + 31492651 = 31492662
59 + 31492603 = 31492662
109 + 31492553 = 31492662
191 + 31492471 = 31492662
233 + 31492429 = 31492662
239 + 31492423 = 31492662
241 + 31492421 = 31492662
263 + 31492399 = 31492662

Showing the first eight; more decompositions exist.
