Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705100, here are decompositions:

7 + 8705093 = 8705100
13 + 8705087 = 8705100
23 + 8705077 = 8705100
31 + 8705069 = 8705100
43 + 8705057 = 8705100
59 + 8705041 = 8705100
67 + 8705033 = 8705100
71 + 8705029 = 8705100

Showing the first eight; more decompositions exist.
