Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558696, here are decompositions:

3 + 31558693 = 31558696
23 + 31558673 = 31558696
47 + 31558649 = 31558696
89 + 31558607 = 31558696
167 + 31558529 = 31558696
227 + 31558469 = 31558696
233 + 31558463 = 31558696
263 + 31558433 = 31558696

Showing the first eight; more decompositions exist.
