Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613708, here are decompositions:

79 + 31613629 = 31613708
127 + 31613581 = 31613708
157 + 31613551 = 31613708
271 + 31613437 = 31613708
307 + 31613401 = 31613708
331 + 31613377 = 31613708
367 + 31613341 = 31613708
571 + 31613137 = 31613708

Showing the first eight; more decompositions exist.
