Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620848, here are decompositions:

7 + 8620841 = 8620848
101 + 8620747 = 8620848
109 + 8620739 = 8620848
127 + 8620721 = 8620848
157 + 8620691 = 8620848
211 + 8620637 = 8620848
227 + 8620621 = 8620848
277 + 8620571 = 8620848

Showing the first eight; more decompositions exist.
