Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623770, here are decompositions:

7 + 8623763 = 8623770
13 + 8623757 = 8623770
19 + 8623751 = 8623770
41 + 8623729 = 8623770
53 + 8623717 = 8623770
83 + 8623687 = 8623770
109 + 8623661 = 8623770
131 + 8623639 = 8623770

Showing the first eight; more decompositions exist.
