Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559296, here are decompositions:

89 + 31559207 = 31559296
107 + 31559189 = 31559296
227 + 31559069 = 31559296
269 + 31559027 = 31559296
449 + 31558847 = 31559296
563 + 31558733 = 31559296
647 + 31558649 = 31559296
677 + 31558619 = 31559296

Showing the first eight; more decompositions exist.
