Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623836, here are decompositions:

5 + 8623831 = 8623836
29 + 8623807 = 8623836
37 + 8623799 = 8623836
43 + 8623793 = 8623836
73 + 8623763 = 8623836
79 + 8623757 = 8623836
107 + 8623729 = 8623836
149 + 8623687 = 8623836

Showing the first eight; more decompositions exist.
