Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613544, here are decompositions:

5 + 31613539 = 31613544
31 + 31613513 = 31613544
103 + 31613441 = 31613544
107 + 31613437 = 31613544
167 + 31613377 = 31613544
211 + 31613333 = 31613544
317 + 31613227 = 31613544
353 + 31613191 = 31613544

Showing the first eight; more decompositions exist.
