Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599982, here are decompositions:

5 + 31599977 = 31599982
23 + 31599959 = 31599982
41 + 31599941 = 31599982
53 + 31599929 = 31599982
173 + 31599809 = 31599982
311 + 31599671 = 31599982
353 + 31599629 = 31599982
383 + 31599599 = 31599982

Showing the first eight; more decompositions exist.
