Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494812, here are decompositions:

3 + 31494809 = 31494812
31 + 31494781 = 31494812
43 + 31494769 = 31494812
229 + 31494583 = 31494812
373 + 31494439 = 31494812
571 + 31494241 = 31494812
733 + 31494079 = 31494812
823 + 31493989 = 31494812

Showing the first eight; more decompositions exist.
