Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559314, here are decompositions:

107 + 31559207 = 31559314
233 + 31559081 = 31559314
263 + 31559051 = 31559314
317 + 31558997 = 31559314
431 + 31558883 = 31559314
467 + 31558847 = 31559314
491 + 31558823 = 31559314
641 + 31558673 = 31559314

Showing the first eight; more decompositions exist.
