Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599486, here are decompositions:

47 + 31599439 = 31599486
97 + 31599389 = 31599486
137 + 31599349 = 31599486
173 + 31599313 = 31599486
179 + 31599307 = 31599486
227 + 31599259 = 31599486
239 + 31599247 = 31599486
293 + 31599193 = 31599486

Showing the first eight; more decompositions exist.
