Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456502, here are decompositions:

61 + 31456441 = 31456502
73 + 31456429 = 31456502
211 + 31456291 = 31456502
223 + 31456279 = 31456502
283 + 31456219 = 31456502
379 + 31456123 = 31456502
409 + 31456093 = 31456502
499 + 31456003 = 31456502

Showing the first eight; more decompositions exist.
