Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462812, here are decompositions:

5 + 31462807 = 31462812
19 + 31462793 = 31462812
41 + 31462771 = 31462812
53 + 31462759 = 31462812
61 + 31462751 = 31462812
83 + 31462729 = 31462812
89 + 31462723 = 31462812
163 + 31462649 = 31462812

Showing the first eight; more decompositions exist.
