Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620738, here are decompositions:

11 + 8620727 = 8620738
17 + 8620721 = 8620738
47 + 8620691 = 8620738
101 + 8620637 = 8620738
107 + 8620631 = 8620738
149 + 8620589 = 8620738
167 + 8620571 = 8620738
239 + 8620499 = 8620738

Showing the first eight; more decompositions exist.
