Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559996, here are decompositions:

7 + 31559989 = 31559996
19 + 31559977 = 31559996
163 + 31559833 = 31559996
277 + 31559719 = 31559996
337 + 31559659 = 31559996
373 + 31559623 = 31559996
613 + 31559383 = 31559996
733 + 31559263 = 31559996

Showing the first eight; more decompositions exist.
