Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601686, here are decompositions:

3 + 8601683 = 8601686
19 + 8601667 = 8601686
229 + 8601457 = 8601686
397 + 8601289 = 8601686
409 + 8601277 = 8601686
433 + 8601253 = 8601686
523 + 8601163 = 8601686
673 + 8601013 = 8601686

Showing the first eight; more decompositions exist.
