Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456514, here are decompositions:

13 + 31456501 = 31456514
73 + 31456441 = 31456514
223 + 31456291 = 31456514
277 + 31456237 = 31456514
421 + 31456093 = 31456514
613 + 31455901 = 31456514
673 + 31455841 = 31456514
787 + 31455727 = 31456514

Showing the first eight; more decompositions exist.
