Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475726, here are decompositions:

13 + 31475713 = 31475726
43 + 31475683 = 31475726
103 + 31475623 = 31475726
127 + 31475599 = 31475726
283 + 31475443 = 31475726
409 + 31475317 = 31475726
439 + 31475287 = 31475726
619 + 31475107 = 31475726

Showing the first eight; more decompositions exist.
