Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623748, here are decompositions:

19 + 8623729 = 8623748
31 + 8623717 = 8623748
61 + 8623687 = 8623748
97 + 8623651 = 8623748
109 + 8623639 = 8623748
127 + 8623621 = 8623748
229 + 8623519 = 8623748
409 + 8623339 = 8623748

Showing the first eight; more decompositions exist.
