Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620764, here are decompositions:

7 + 8620757 = 8620764
17 + 8620747 = 8620764
37 + 8620727 = 8620764
41 + 8620723 = 8620764
43 + 8620721 = 8620764
73 + 8620691 = 8620764
101 + 8620663 = 8620764
127 + 8620637 = 8620764

Showing the first eight; more decompositions exist.
