Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599672, here are decompositions:

19 + 31599653 = 31599672
23 + 31599649 = 31599672
43 + 31599629 = 31599672
61 + 31599611 = 31599672
73 + 31599599 = 31599672
109 + 31599563 = 31599672
173 + 31599499 = 31599672
233 + 31599439 = 31599672

Showing the first eight; more decompositions exist.
