Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559726, here are decompositions:

7 + 31559719 = 31559726
67 + 31559659 = 31559726
73 + 31559653 = 31559726
103 + 31559623 = 31559726
283 + 31559443 = 31559726
313 + 31559413 = 31559726
409 + 31559317 = 31559726
463 + 31559263 = 31559726

Showing the first eight; more decompositions exist.
