Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457034, here are decompositions:

97 + 31456937 = 31457034
107 + 31456927 = 31457034
131 + 31456903 = 31457034
151 + 31456883 = 31457034
293 + 31456741 = 31457034
307 + 31456727 = 31457034
313 + 31456721 = 31457034
331 + 31456703 = 31457034

Showing the first eight; more decompositions exist.
