Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569924, here are decompositions:

41 + 31569883 = 31569924
73 + 31569851 = 31569924
131 + 31569793 = 31569924
157 + 31569767 = 31569924
163 + 31569761 = 31569924
173 + 31569751 = 31569924
223 + 31569701 = 31569924
233 + 31569691 = 31569924

Showing the first eight; more decompositions exist.
