Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623730, here are decompositions:

13 + 8623717 = 8623730
43 + 8623687 = 8623730
79 + 8623651 = 8623730
109 + 8623621 = 8623730
127 + 8623603 = 8623730
151 + 8623579 = 8623730
211 + 8623519 = 8623730
307 + 8623423 = 8623730

Showing the first eight; more decompositions exist.
