Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596958, here are decompositions:

59 + 31596899 = 31596958
101 + 31596857 = 31596958
137 + 31596821 = 31596958
251 + 31596707 = 31596958
347 + 31596611 = 31596958
461 + 31596497 = 31596958
521 + 31596437 = 31596958
557 + 31596401 = 31596958

Showing the first eight; more decompositions exist.
