Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614528, here are decompositions:

5 + 31614523 = 31614528
79 + 31614449 = 31614528
151 + 31614377 = 31614528
157 + 31614371 = 31614528
251 + 31614277 = 31614528
311 + 31614217 = 31614528
317 + 31614211 = 31614528
331 + 31614197 = 31614528

Showing the first eight; more decompositions exist.
