Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457374, here are decompositions:

71 + 31457303 = 31457374
107 + 31457267 = 31457374
173 + 31457201 = 31457374
281 + 31457093 = 31457374
293 + 31457081 = 31457374
491 + 31456883 = 31457374
587 + 31456787 = 31457374
593 + 31456781 = 31457374

Showing the first eight; more decompositions exist.
