Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626782, here are decompositions:

73 + 31626709 = 31626782
163 + 31626619 = 31626782
193 + 31626589 = 31626782
211 + 31626571 = 31626782
283 + 31626499 = 31626782
673 + 31626109 = 31626782
709 + 31626073 = 31626782
829 + 31625953 = 31626782

Showing the first eight; more decompositions exist.
