Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456534, here are decompositions:

3 + 31456531 = 31456534
17 + 31456517 = 31456534
47 + 31456487 = 31456534
173 + 31456361 = 31456534
257 + 31456277 = 31456534
293 + 31456241 = 31456534
467 + 31456067 = 31456534
521 + 31456013 = 31456534

Showing the first eight; more decompositions exist.
