Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615758, here are decompositions:

17 + 31615741 = 31615758
29 + 31615729 = 31615758
47 + 31615711 = 31615758
89 + 31615669 = 31615758
107 + 31615651 = 31615758
149 + 31615609 = 31615758
269 + 31615489 = 31615758
281 + 31615477 = 31615758

Showing the first eight; more decompositions exist.
