Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464874, here are decompositions:

47 + 31464827 = 31464874
53 + 31464821 = 31464874
173 + 31464701 = 31464874
257 + 31464617 = 31464874
293 + 31464581 = 31464874
317 + 31464557 = 31464874
431 + 31464443 = 31464874
593 + 31464281 = 31464874

Showing the first eight; more decompositions exist.
