Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476656, here are decompositions:

109 + 31476547 = 31476656
139 + 31476517 = 31476656
157 + 31476499 = 31476656
199 + 31476457 = 31476656
223 + 31476433 = 31476656
283 + 31476373 = 31476656
307 + 31476349 = 31476656
313 + 31476343 = 31476656

Showing the first eight; more decompositions exist.
