Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596508, here are decompositions:

11 + 31596497 = 31596508
71 + 31596437 = 31596508
89 + 31596419 = 31596508
107 + 31596401 = 31596508
191 + 31596317 = 31596508
197 + 31596311 = 31596508
389 + 31596119 = 31596508
467 + 31596041 = 31596508

Showing the first eight; more decompositions exist.
