Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601878, here are decompositions:

139 + 8601739 = 8601878
151 + 8601727 = 8601878
211 + 8601667 = 8601878
367 + 8601511 = 8601878
379 + 8601499 = 8601878
421 + 8601457 = 8601878
457 + 8601421 = 8601878
487 + 8601391 = 8601878

Showing the first eight; more decompositions exist.
