Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456024, here are decompositions:

3 + 31456021 = 31456024
11 + 31456013 = 31456024
263 + 31455761 = 31456024
311 + 31455713 = 31456024
401 + 31455623 = 31456024
491 + 31455533 = 31456024
503 + 31455521 = 31456024
521 + 31455503 = 31456024

Showing the first eight; more decompositions exist.
