Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599510, here are decompositions:

11 + 31599499 = 31599510
23 + 31599487 = 31599510
71 + 31599439 = 31599510
79 + 31599431 = 31599510
157 + 31599353 = 31599510
197 + 31599313 = 31599510
251 + 31599259 = 31599510
263 + 31599247 = 31599510

Showing the first eight; more decompositions exist.
