Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493464, here are decompositions:

17 + 31493447 = 31493464
173 + 31493291 = 31493464
263 + 31493201 = 31493464
293 + 31493171 = 31493464
311 + 31493153 = 31493464
467 + 31492997 = 31493464
521 + 31492943 = 31493464
557 + 31492907 = 31493464

Showing the first eight; more decompositions exist.
