Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741686, here are decompositions:

3 + 8741683 = 8741686
47 + 8741639 = 8741686
227 + 8741459 = 8741686
293 + 8741393 = 8741686
383 + 8741303 = 8741686
557 + 8741129 = 8741686
563 + 8741123 = 8741686
587 + 8741099 = 8741686

Showing the first eight; more decompositions exist.
