Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468824, here are decompositions:

31 + 31468793 = 31468824
47 + 31468777 = 31468824
67 + 31468757 = 31468824
97 + 31468727 = 31468824
157 + 31468667 = 31468824
193 + 31468631 = 31468824
227 + 31468597 = 31468824
251 + 31468573 = 31468824

Showing the first eight; more decompositions exist.
