Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585414, here are decompositions:

53 + 31585361 = 31585414
71 + 31585343 = 31585414
83 + 31585331 = 31585414
101 + 31585313 = 31585414
197 + 31585217 = 31585414
233 + 31585181 = 31585414
347 + 31585067 = 31585414
353 + 31585061 = 31585414

Showing the first eight; more decompositions exist.
