Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617354, here are decompositions:

61 + 31617293 = 31617354
71 + 31617283 = 31617354
73 + 31617281 = 31617354
101 + 31617253 = 31617354
103 + 31617251 = 31617354
173 + 31617181 = 31617354
277 + 31617077 = 31617354
281 + 31617073 = 31617354

Showing the first eight; more decompositions exist.
