Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596628, here are decompositions:

17 + 31596611 = 31596628
131 + 31596497 = 31596628
191 + 31596437 = 31596628
227 + 31596401 = 31596628
311 + 31596317 = 31596628
317 + 31596311 = 31596628
419 + 31596209 = 31596628
509 + 31596119 = 31596628

Showing the first eight; more decompositions exist.
