Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601866, here are decompositions:

43 + 8601823 = 8601866
127 + 8601739 = 8601866
139 + 8601727 = 8601866
199 + 8601667 = 8601866
367 + 8601499 = 8601866
409 + 8601457 = 8601866
523 + 8601343 = 8601866
577 + 8601289 = 8601866

Showing the first eight; more decompositions exist.
