Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612794, here are decompositions:

41 + 31612753 = 31612794
47 + 31612747 = 31612794
61 + 31612733 = 31612794
67 + 31612727 = 31612794
127 + 31612667 = 31612794
131 + 31612663 = 31612794
167 + 31612627 = 31612794
173 + 31612621 = 31612794

Showing the first eight; more decompositions exist.
