Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608994, here are decompositions:

23 + 31608971 = 31608994
41 + 31608953 = 31608994
83 + 31608911 = 31608994
101 + 31608893 = 31608994
107 + 31608887 = 31608994
173 + 31608821 = 31608994
257 + 31608737 = 31608994
281 + 31608713 = 31608994

Showing the first eight; more decompositions exist.
