Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617994, here are decompositions:

41 + 31617953 = 31617994
53 + 31617941 = 31617994
131 + 31617863 = 31617994
167 + 31617827 = 31617994
197 + 31617797 = 31617994
281 + 31617713 = 31617994
431 + 31617563 = 31617994
461 + 31617533 = 31617994

Showing the first eight; more decompositions exist.
