Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599732, here are decompositions:

5 + 31599727 = 31599732
29 + 31599703 = 31599732
61 + 31599671 = 31599732
79 + 31599653 = 31599732
83 + 31599649 = 31599732
103 + 31599629 = 31599732
179 + 31599553 = 31599732
181 + 31599551 = 31599732

Showing the first eight; more decompositions exist.
