Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514346, here are decompositions:

37 + 31514309 = 31514346
79 + 31514267 = 31514346
107 + 31514239 = 31514346
197 + 31514149 = 31514346
233 + 31514113 = 31514346
359 + 31513987 = 31514346
379 + 31513967 = 31514346
389 + 31513957 = 31514346

Showing the first eight; more decompositions exist.
