Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623916, here are decompositions:

13 + 8623903 = 8623916
19 + 8623897 = 8623916
73 + 8623843 = 8623916
109 + 8623807 = 8623916
199 + 8623717 = 8623916
229 + 8623687 = 8623916
277 + 8623639 = 8623916
313 + 8623603 = 8623916

Showing the first eight; more decompositions exist.
