Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623812, here are decompositions:

5 + 8623807 = 8623812
11 + 8623801 = 8623812
13 + 8623799 = 8623812
19 + 8623793 = 8623812
61 + 8623751 = 8623812
83 + 8623729 = 8623812
151 + 8623661 = 8623812
173 + 8623639 = 8623812

Showing the first eight; more decompositions exist.
