Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494682, here are decompositions:

3 + 31494679 = 31494682
71 + 31494611 = 31494682
101 + 31494581 = 31494682
173 + 31494509 = 31494682
179 + 31494503 = 31494682
239 + 31494443 = 31494682
251 + 31494431 = 31494682
281 + 31494401 = 31494682

Showing the first eight; more decompositions exist.
