Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596028, here are decompositions:

59 + 31595969 = 31596028
197 + 31595831 = 31596028
251 + 31595777 = 31596028
257 + 31595771 = 31596028
311 + 31595717 = 31596028
461 + 31595567 = 31596028
641 + 31595387 = 31596028
809 + 31595219 = 31596028

Showing the first eight; more decompositions exist.
