Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623840, here are decompositions:

41 + 8623799 = 8623840
47 + 8623793 = 8623840
53 + 8623787 = 8623840
83 + 8623757 = 8623840
89 + 8623751 = 8623840
179 + 8623661 = 8623840
257 + 8623583 = 8623840
293 + 8623547 = 8623840

Showing the first eight; more decompositions exist.
