Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613732, here are decompositions:

13 + 31613719 = 31613732
103 + 31613629 = 31613732
109 + 31613623 = 31613732
151 + 31613581 = 31613732
181 + 31613551 = 31613732
193 + 31613539 = 31613732
331 + 31613401 = 31613732
349 + 31613383 = 31613732

Showing the first eight; more decompositions exist.
