Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627378, here are decompositions:

7 + 8627371 = 8627378
37 + 8627341 = 8627378
79 + 8627299 = 8627378
127 + 8627251 = 8627378
211 + 8627167 = 8627378
229 + 8627149 = 8627378
349 + 8627029 = 8627378
379 + 8626999 = 8627378

Showing the first eight; more decompositions exist.
