Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585294, here are decompositions:

5 + 31585289 = 31585294
23 + 31585271 = 31585294
101 + 31585193 = 31585294
113 + 31585181 = 31585294
227 + 31585067 = 31585294
233 + 31585061 = 31585294
347 + 31584947 = 31585294
641 + 31584653 = 31585294

Showing the first eight; more decompositions exist.
