Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613952, here are decompositions:

109 + 31613843 = 31613952
113 + 31613839 = 31613952
151 + 31613801 = 31613952
233 + 31613719 = 31613952
283 + 31613669 = 31613952
313 + 31613639 = 31613952
373 + 31613579 = 31613952
401 + 31613551 = 31613952

Showing the first eight; more decompositions exist.
