Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614438, here are decompositions:

61 + 31614377 = 31614438
67 + 31614371 = 31614438
211 + 31614227 = 31614438
227 + 31614211 = 31614438
239 + 31614199 = 31614438
241 + 31614197 = 31614438
257 + 31614181 = 31614438
277 + 31614161 = 31614438

Showing the first eight; more decompositions exist.
