Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612926, here are decompositions:

13 + 31612913 = 31612926
53 + 31612873 = 31612926
73 + 31612853 = 31612926
167 + 31612759 = 31612926
173 + 31612753 = 31612926
179 + 31612747 = 31612926
193 + 31612733 = 31612926
197 + 31612729 = 31612926

Showing the first eight; more decompositions exist.
