Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663900, here are decompositions:

31 + 8663869 = 8663900
73 + 8663827 = 8663900
79 + 8663821 = 8663900
97 + 8663803 = 8663900
103 + 8663797 = 8663900
181 + 8663719 = 8663900
199 + 8663701 = 8663900
307 + 8663593 = 8663900

Showing the first eight; more decompositions exist.
