Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468156, here are decompositions:

59 + 31468097 = 31468156
89 + 31468067 = 31468156
173 + 31467983 = 31468156
257 + 31467899 = 31468156
263 + 31467893 = 31468156
347 + 31467809 = 31468156
389 + 31467767 = 31468156
479 + 31467677 = 31468156

Showing the first eight; more decompositions exist.
