Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623908, here are decompositions:

5 + 8623903 = 8623908
11 + 8623897 = 8623908
61 + 8623847 = 8623908
101 + 8623807 = 8623908
107 + 8623801 = 8623908
109 + 8623799 = 8623908
151 + 8623757 = 8623908
157 + 8623751 = 8623908

Showing the first eight; more decompositions exist.
