Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504088, here are decompositions:

37 + 31504051 = 31504088
127 + 31503961 = 31504088
157 + 31503931 = 31504088
241 + 31503847 = 31504088
277 + 31503811 = 31504088
337 + 31503751 = 31504088
457 + 31503631 = 31504088
619 + 31503469 = 31504088

Showing the first eight; more decompositions exist.
