Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613614, here are decompositions:

101 + 31613513 = 31613614
173 + 31613441 = 31613614
257 + 31613357 = 31613614
281 + 31613333 = 31613614
443 + 31613171 = 31613614
587 + 31613027 = 31613614
653 + 31612961 = 31613614
701 + 31612913 = 31613614

Showing the first eight; more decompositions exist.
