Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613896, here are decompositions:

29 + 31613867 = 31613896
53 + 31613843 = 31613896
89 + 31613807 = 31613896
113 + 31613783 = 31613896
179 + 31613717 = 31613896
227 + 31613669 = 31613896
257 + 31613639 = 31613896
269 + 31613627 = 31613896

Showing the first eight; more decompositions exist.
