Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516774, here are decompositions:

17 + 31516757 = 31516774
71 + 31516703 = 31516774
251 + 31516523 = 31516774
281 + 31516493 = 31516774
347 + 31516427 = 31516774
521 + 31516253 = 31516774
617 + 31516157 = 31516774
881 + 31515893 = 31516774

Showing the first eight; more decompositions exist.
