Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477088, here are decompositions:

31 + 31477057 = 31477088
37 + 31477051 = 31477088
61 + 31477027 = 31477088
67 + 31477021 = 31477088
157 + 31476931 = 31477088
241 + 31476847 = 31477088
397 + 31476691 = 31477088
457 + 31476631 = 31477088

Showing the first eight; more decompositions exist.
