Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514080, here are decompositions:

113 + 31513967 = 31514080
137 + 31513943 = 31514080
263 + 31513817 = 31514080
293 + 31513787 = 31514080
359 + 31513721 = 31514080
383 + 31513697 = 31514080
419 + 31513661 = 31514080
467 + 31513613 = 31514080

Showing the first eight; more decompositions exist.
