Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599546, here are decompositions:

47 + 31599499 = 31599546
59 + 31599487 = 31599546
107 + 31599439 = 31599546
157 + 31599389 = 31599546
193 + 31599353 = 31599546
197 + 31599349 = 31599546
233 + 31599313 = 31599546
239 + 31599307 = 31599546

Showing the first eight; more decompositions exist.
