Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494732, here are decompositions:

11 + 31494721 = 31494732
19 + 31494713 = 31494732
41 + 31494691 = 31494732
43 + 31494689 = 31494732
53 + 31494679 = 31494732
89 + 31494643 = 31494732
149 + 31494583 = 31494732
151 + 31494581 = 31494732

Showing the first eight; more decompositions exist.
