Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456714, here are decompositions:

11 + 31456703 = 31456714
167 + 31456547 = 31456714
197 + 31456517 = 31456714
227 + 31456487 = 31456714
353 + 31456361 = 31456714
383 + 31456331 = 31456714
467 + 31456247 = 31456714
521 + 31456193 = 31456714

Showing the first eight; more decompositions exist.
