Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559746, here are decompositions:

47 + 31559699 = 31559746
59 + 31559687 = 31559746
107 + 31559639 = 31559746
173 + 31559573 = 31559746
557 + 31559189 = 31559746
653 + 31559093 = 31559746
677 + 31559069 = 31559746
719 + 31559027 = 31559746

Showing the first eight; more decompositions exist.
