Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496656, here are decompositions:

83 + 31496573 = 31496656
89 + 31496567 = 31496656
137 + 31496519 = 31496656
167 + 31496489 = 31496656
227 + 31496429 = 31496656
239 + 31496417 = 31496656
557 + 31496099 = 31496656
599 + 31496057 = 31496656

Showing the first eight; more decompositions exist.
