Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620918, here are decompositions:

71 + 8620847 = 8620918
179 + 8620739 = 8620918
191 + 8620727 = 8620918
197 + 8620721 = 8620918
227 + 8620691 = 8620918
281 + 8620637 = 8620918
347 + 8620571 = 8620918
389 + 8620529 = 8620918

Showing the first eight; more decompositions exist.
