Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586792, here are decompositions:

73 + 31586719 = 31586792
103 + 31586689 = 31586792
283 + 31586509 = 31586792
331 + 31586461 = 31586792
661 + 31586131 = 31586792
691 + 31586101 = 31586792
733 + 31586059 = 31586792
739 + 31586053 = 31586792

Showing the first eight; more decompositions exist.
