Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613956, here are decompositions:

29 + 31613927 = 31613956
89 + 31613867 = 31613956
113 + 31613843 = 31613956
137 + 31613819 = 31613956
149 + 31613807 = 31613956
173 + 31613783 = 31613956
239 + 31613717 = 31613956
317 + 31613639 = 31613956

Showing the first eight; more decompositions exist.
