Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620740, here are decompositions:

13 + 8620727 = 8620740
17 + 8620723 = 8620740
19 + 8620721 = 8620740
53 + 8620687 = 8620740
67 + 8620673 = 8620740
101 + 8620639 = 8620740
103 + 8620637 = 8620740
109 + 8620631 = 8620740

Showing the first eight; more decompositions exist.
