Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559308, here are decompositions:

89 + 31559219 = 31559308
101 + 31559207 = 31559308
227 + 31559081 = 31559308
239 + 31559069 = 31559308
257 + 31559051 = 31559308
281 + 31559027 = 31559308
311 + 31558997 = 31559308
449 + 31558859 = 31559308

Showing the first eight; more decompositions exist.
