Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613324, here are decompositions:

97 + 31613227 = 31613324
181 + 31613143 = 31613324
271 + 31613053 = 31613324
373 + 31612951 = 31613324
433 + 31612891 = 31613324
571 + 31612753 = 31613324
577 + 31612747 = 31613324
661 + 31612663 = 31613324

Showing the first eight; more decompositions exist.
