Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613832, here are decompositions:

13 + 31613819 = 31613832
31 + 31613801 = 31613832
113 + 31613719 = 31613832
163 + 31613669 = 31613832
193 + 31613639 = 31613832
251 + 31613581 = 31613832
281 + 31613551 = 31613832
293 + 31613539 = 31613832

Showing the first eight; more decompositions exist.
