Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617760, here are decompositions:

3 + 31617757 = 31617760
47 + 31617713 = 31617760
71 + 31617689 = 31617760
101 + 31617659 = 31617760
131 + 31617629 = 31617760
173 + 31617587 = 31617760
197 + 31617563 = 31617760
227 + 31617533 = 31617760

Showing the first eight; more decompositions exist.
