Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468066, here are decompositions:

53 + 31468013 = 31468066
83 + 31467983 = 31468066
167 + 31467899 = 31468066
173 + 31467893 = 31468066
257 + 31467809 = 31468066
347 + 31467719 = 31468066
389 + 31467677 = 31468066
419 + 31467647 = 31468066

Showing the first eight; more decompositions exist.
