Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596890, here are decompositions:

7 + 31596883 = 31596890
43 + 31596847 = 31596890
97 + 31596793 = 31596890
139 + 31596751 = 31596890
181 + 31596709 = 31596890
211 + 31596679 = 31596890
229 + 31596661 = 31596890
277 + 31596613 = 31596890

Showing the first eight; more decompositions exist.
