Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468836, here are decompositions:

13 + 31468823 = 31468836
43 + 31468793 = 31468836
59 + 31468777 = 31468836
79 + 31468757 = 31468836
109 + 31468727 = 31468836
137 + 31468699 = 31468836
199 + 31468637 = 31468836
239 + 31468597 = 31468836

Showing the first eight; more decompositions exist.
