Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494514, here are decompositions:

5 + 31494509 = 31494514
11 + 31494503 = 31494514
17 + 31494497 = 31494514
47 + 31494467 = 31494514
71 + 31494443 = 31494514
83 + 31494431 = 31494514
113 + 31494401 = 31494514
167 + 31494347 = 31494514

Showing the first eight; more decompositions exist.
