Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494744, here are decompositions:

7 + 31494737 = 31494744
23 + 31494721 = 31494744
31 + 31494713 = 31494744
37 + 31494707 = 31494744
53 + 31494691 = 31494744
101 + 31494643 = 31494744
107 + 31494637 = 31494744
163 + 31494581 = 31494744

Showing the first eight; more decompositions exist.
