Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476686, here are decompositions:

79 + 31476607 = 31476686
139 + 31476547 = 31476686
229 + 31476457 = 31476686
313 + 31476373 = 31476686
337 + 31476349 = 31476686
499 + 31476187 = 31476686
613 + 31476073 = 31476686
673 + 31476013 = 31476686

Showing the first eight; more decompositions exist.
