Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549024, here are decompositions:

5 + 31549019 = 31549024
41 + 31548983 = 31549024
71 + 31548953 = 31549024
167 + 31548857 = 31549024
257 + 31548767 = 31549024
281 + 31548743 = 31549024
347 + 31548677 = 31549024
383 + 31548641 = 31549024

Showing the first eight; more decompositions exist.
