Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456592, here are decompositions:

3 + 31456589 = 31456592
61 + 31456531 = 31456592
151 + 31456441 = 31456592
163 + 31456429 = 31456592
313 + 31456279 = 31456592
373 + 31456219 = 31456592
499 + 31456093 = 31456592
571 + 31456021 = 31456592

Showing the first eight; more decompositions exist.
