Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612914, here are decompositions:

23 + 31612891 = 31612914
41 + 31612873 = 31612914
61 + 31612853 = 31612914
83 + 31612831 = 31612914
167 + 31612747 = 31612914
181 + 31612733 = 31612914
251 + 31612663 = 31612914
293 + 31612621 = 31612914

Showing the first eight; more decompositions exist.
