Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476986, here are decompositions:

139 + 31476847 = 31476986
157 + 31476829 = 31476986
283 + 31476703 = 31476986
379 + 31476607 = 31476986
439 + 31476547 = 31476986
487 + 31476499 = 31476986
613 + 31476373 = 31476986
643 + 31476343 = 31476986

Showing the first eight; more decompositions exist.
