Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613774, here are decompositions:

151 + 31613623 = 31613774
193 + 31613581 = 31613774
223 + 31613551 = 31613774
337 + 31613437 = 31613774
373 + 31613401 = 31613774
397 + 31613377 = 31613774
433 + 31613341 = 31613774
547 + 31613227 = 31613774

Showing the first eight; more decompositions exist.
