Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757918, here are decompositions:

41 + 8757877 = 8757918
61 + 8757857 = 8757918
67 + 8757851 = 8757918
89 + 8757829 = 8757918
97 + 8757821 = 8757918
101 + 8757817 = 8757918
109 + 8757809 = 8757918
149 + 8757769 = 8757918

Showing the first eight; more decompositions exist.
