Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623900, here are decompositions:

3 + 8623897 = 8623900
17 + 8623883 = 8623900
53 + 8623847 = 8623900
101 + 8623799 = 8623900
107 + 8623793 = 8623900
113 + 8623787 = 8623900
137 + 8623763 = 8623900
149 + 8623751 = 8623900

Showing the first eight; more decompositions exist.
