Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689900, here are decompositions:

47 + 8689853 = 8689900
59 + 8689841 = 8689900
83 + 8689817 = 8689900
101 + 8689799 = 8689900
173 + 8689727 = 8689900
227 + 8689673 = 8689900
239 + 8689661 = 8689900
251 + 8689649 = 8689900

Showing the first eight; more decompositions exist.
