Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586762, here are decompositions:

19 + 31586743 = 31586762
43 + 31586719 = 31586762
73 + 31586689 = 31586762
631 + 31586131 = 31586762
661 + 31586101 = 31586762
709 + 31586053 = 31586762
859 + 31585903 = 31586762
1213 + 31585549 = 31586762

Showing the first eight; more decompositions exist.
