Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494502, here are decompositions:

5 + 31494497 = 31494502
23 + 31494479 = 31494502
59 + 31494443 = 31494502
71 + 31494431 = 31494502
101 + 31494401 = 31494502
113 + 31494389 = 31494502
239 + 31494263 = 31494502
359 + 31494143 = 31494502

Showing the first eight; more decompositions exist.
