Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494556, here are decompositions:

3 + 31494553 = 31494556
47 + 31494509 = 31494556
53 + 31494503 = 31494556
59 + 31494497 = 31494556
89 + 31494467 = 31494556
113 + 31494443 = 31494556
167 + 31494389 = 31494556
263 + 31494293 = 31494556

Showing the first eight; more decompositions exist.
