Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514336, here are decompositions:

97 + 31514239 = 31514336
193 + 31514143 = 31514336
223 + 31514113 = 31514336
277 + 31514059 = 31514336
313 + 31514023 = 31514336
349 + 31513987 = 31514336
379 + 31513957 = 31514336
409 + 31513927 = 31514336

Showing the first eight; more decompositions exist.
