Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608892, here are decompositions:

5 + 31608887 = 31608892
41 + 31608851 = 31608892
71 + 31608821 = 31608892
113 + 31608779 = 31608892
179 + 31608713 = 31608892
443 + 31608449 = 31608892
743 + 31608149 = 31608892
761 + 31608131 = 31608892

Showing the first eight; more decompositions exist.
