Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494696, here are decompositions:

5 + 31494691 = 31494696
7 + 31494689 = 31494696
17 + 31494679 = 31494696
53 + 31494643 = 31494696
59 + 31494637 = 31494696
113 + 31494583 = 31494696
193 + 31494503 = 31494696
199 + 31494497 = 31494696

Showing the first eight; more decompositions exist.
