Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596778, here are decompositions:

29 + 31596749 = 31596778
71 + 31596707 = 31596778
107 + 31596671 = 31596778
167 + 31596611 = 31596778
281 + 31596497 = 31596778
359 + 31596419 = 31596778
461 + 31596317 = 31596778
467 + 31596311 = 31596778

Showing the first eight; more decompositions exist.
