Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468710, here are decompositions:

11 + 31468699 = 31468710
43 + 31468667 = 31468710
73 + 31468637 = 31468710
79 + 31468631 = 31468710
113 + 31468597 = 31468710
137 + 31468573 = 31468710
139 + 31468571 = 31468710
151 + 31468559 = 31468710

Showing the first eight; more decompositions exist.
