Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639700, here are decompositions:

37 + 8639663 = 8639700
53 + 8639647 = 8639700
61 + 8639639 = 8639700
101 + 8639599 = 8639700
103 + 8639597 = 8639700
109 + 8639591 = 8639700
137 + 8639563 = 8639700
149 + 8639551 = 8639700

Showing the first eight; more decompositions exist.
