Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468906, here are decompositions:

3 + 31468903 = 31468906
5 + 31468901 = 31468906
83 + 31468823 = 31468906
113 + 31468793 = 31468906
149 + 31468757 = 31468906
179 + 31468727 = 31468906
239 + 31468667 = 31468906
269 + 31468637 = 31468906

Showing the first eight; more decompositions exist.
