Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456616, here are decompositions:

19 + 31456597 = 31456616
337 + 31456279 = 31456616
379 + 31456237 = 31456616
397 + 31456219 = 31456616
523 + 31456093 = 31456616
613 + 31456003 = 31456616
727 + 31455889 = 31456616
739 + 31455877 = 31456616

Showing the first eight; more decompositions exist.
