Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654786, here are decompositions:

13 + 8654773 = 8654786
37 + 8654749 = 8654786
73 + 8654713 = 8654786
97 + 8654689 = 8654786
223 + 8654563 = 8654786
397 + 8654389 = 8654786
487 + 8654299 = 8654786
499 + 8654287 = 8654786

Showing the first eight; more decompositions exist.
