Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614396, here are decompositions:

19 + 31614377 = 31614396
43 + 31614353 = 31614396
53 + 31614343 = 31614396
113 + 31614283 = 31614396
167 + 31614229 = 31614396
179 + 31614217 = 31614396
197 + 31614199 = 31614396
199 + 31614197 = 31614396

Showing the first eight; more decompositions exist.
