Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608952, here are decompositions:

41 + 31608911 = 31608952
59 + 31608893 = 31608952
101 + 31608851 = 31608952
131 + 31608821 = 31608952
173 + 31608779 = 31608952
239 + 31608713 = 31608952
503 + 31608449 = 31608952
821 + 31608131 = 31608952

Showing the first eight; more decompositions exist.
