Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627228, here are decompositions:

37 + 8627191 = 8627228
61 + 8627167 = 8627228
67 + 8627161 = 8627228
79 + 8627149 = 8627228
109 + 8627119 = 8627228
199 + 8627029 = 8627228
229 + 8626999 = 8627228
367 + 8626861 = 8627228

Showing the first eight; more decompositions exist.
