Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613492, here are decompositions:

109 + 31613383 = 31613492
151 + 31613341 = 31613492
349 + 31613143 = 31613492
373 + 31613119 = 31613492
439 + 31613053 = 31613492
523 + 31612969 = 31613492
541 + 31612951 = 31613492
601 + 31612891 = 31613492

Showing the first eight; more decompositions exist.
