Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468684, here are decompositions:

17 + 31468667 = 31468684
47 + 31468637 = 31468684
53 + 31468631 = 31468684
113 + 31468571 = 31468684
131 + 31468553 = 31468684
167 + 31468517 = 31468684
173 + 31468511 = 31468684
281 + 31468403 = 31468684

Showing the first eight; more decompositions exist.
