Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613748, here are decompositions:

29 + 31613719 = 31613748
31 + 31613717 = 31613748
79 + 31613669 = 31613748
109 + 31613639 = 31613748
167 + 31613581 = 31613748
197 + 31613551 = 31613748
307 + 31613441 = 31613748
311 + 31613437 = 31613748

Showing the first eight; more decompositions exist.
