Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599498, here are decompositions:

11 + 31599487 = 31599498
59 + 31599439 = 31599498
67 + 31599431 = 31599498
109 + 31599389 = 31599498
149 + 31599349 = 31599498
157 + 31599341 = 31599498
191 + 31599307 = 31599498
239 + 31599259 = 31599498

Showing the first eight; more decompositions exist.
