Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477100, here are decompositions:

37 + 31477063 = 31477100
43 + 31477057 = 31477100
73 + 31477027 = 31477100
79 + 31477021 = 31477100
229 + 31476871 = 31477100
271 + 31476829 = 31477100
367 + 31476733 = 31477100
373 + 31476727 = 31477100

Showing the first eight; more decompositions exist.
