Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492702, here are decompositions:

5 + 31492697 = 31492702
11 + 31492691 = 31492702
149 + 31492553 = 31492702
173 + 31492529 = 31492702
281 + 31492421 = 31492702
383 + 31492319 = 31492702
443 + 31492259 = 31492702
641 + 31492061 = 31492702

Showing the first eight; more decompositions exist.
