Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623790, here are decompositions:

3 + 8623787 = 8623790
61 + 8623729 = 8623790
73 + 8623717 = 8623790
103 + 8623687 = 8623790
139 + 8623651 = 8623790
151 + 8623639 = 8623790
211 + 8623579 = 8623790
271 + 8623519 = 8623790

Showing the first eight; more decompositions exist.
