Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599492, here are decompositions:

5 + 31599487 = 31599492
53 + 31599439 = 31599492
61 + 31599431 = 31599492
103 + 31599389 = 31599492
139 + 31599353 = 31599492
151 + 31599341 = 31599492
179 + 31599313 = 31599492
233 + 31599259 = 31599492

Showing the first eight; more decompositions exist.
