Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617852, here are decompositions:

41 + 31617811 = 31617852
89 + 31617763 = 31617852
139 + 31617713 = 31617852
163 + 31617689 = 31617852
173 + 31617679 = 31617852
179 + 31617673 = 31617852
193 + 31617659 = 31617852
223 + 31617629 = 31617852

Showing the first eight; more decompositions exist.
