Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79640, here are decompositions:

7 + 79633 = 79640
13 + 79627 = 79640
19 + 79621 = 79640
31 + 79609 = 79640
61 + 79579 = 79640
79 + 79561 = 79640
103 + 79537 = 79640
109 + 79531 = 79640

Showing the first eight; more decompositions exist.
