Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601806, here are decompositions:

67 + 8601739 = 8601806
79 + 8601727 = 8601806
139 + 8601667 = 8601806
307 + 8601499 = 8601806
349 + 8601457 = 8601806
463 + 8601343 = 8601806
643 + 8601163 = 8601806
709 + 8601097 = 8601806

Showing the first eight; more decompositions exist.
