Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596238, here are decompositions:

29 + 31596209 = 31596238
197 + 31596041 = 31596238
269 + 31595969 = 31596238
431 + 31595807 = 31596238
461 + 31595777 = 31596238
467 + 31595771 = 31596238
521 + 31595717 = 31596238
1019 + 31595219 = 31596238

Showing the first eight; more decompositions exist.
