Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619056, here are decompositions:

47 + 31619009 = 31619056
107 + 31618949 = 31619056
113 + 31618943 = 31619056
173 + 31618883 = 31619056
233 + 31618823 = 31619056
353 + 31618703 = 31619056
419 + 31618637 = 31619056
509 + 31618547 = 31619056

Showing the first eight; more decompositions exist.
