Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614540, here are decompositions:

17 + 31614523 = 31614540
47 + 31614493 = 31614540
163 + 31614377 = 31614540
197 + 31614343 = 31614540
257 + 31614283 = 31614540
263 + 31614277 = 31614540
311 + 31614229 = 31614540
313 + 31614227 = 31614540

Showing the first eight; more decompositions exist.
