Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494932, here are decompositions:

13 + 31494919 = 31494932
151 + 31494781 = 31494932
163 + 31494769 = 31494932
211 + 31494721 = 31494932
241 + 31494691 = 31494932
349 + 31494583 = 31494932
379 + 31494553 = 31494932
463 + 31494469 = 31494932

Showing the first eight; more decompositions exist.
