Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599822, here are decompositions:

11 + 31599811 = 31599822
13 + 31599809 = 31599822
41 + 31599781 = 31599822
61 + 31599761 = 31599822
139 + 31599683 = 31599822
151 + 31599671 = 31599822
173 + 31599649 = 31599822
193 + 31599629 = 31599822

Showing the first eight; more decompositions exist.
