Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494674, here are decompositions:

31 + 31494643 = 31494674
37 + 31494637 = 31494674
373 + 31494301 = 31494674
433 + 31494241 = 31494674
577 + 31494097 = 31494674
691 + 31493983 = 31494674
733 + 31493941 = 31494674
823 + 31493851 = 31494674

Showing the first eight; more decompositions exist.
