Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463876, here are decompositions:

19 + 31463857 = 31463876
79 + 31463797 = 31463876
97 + 31463779 = 31463876
109 + 31463767 = 31463876
163 + 31463713 = 31463876
349 + 31463527 = 31463876
487 + 31463389 = 31463876
523 + 31463353 = 31463876

Showing the first eight; more decompositions exist.
