Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655850, here are decompositions:

41 + 8655809 = 8655850
89 + 8655761 = 8655850
101 + 8655749 = 8655850
131 + 8655719 = 8655850
149 + 8655701 = 8655850
173 + 8655677 = 8655850
179 + 8655671 = 8655850
197 + 8655653 = 8655850

Showing the first eight; more decompositions exist.
