Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686942, here are decompositions:

41 + 8686901 = 8686942
53 + 8686889 = 8686942
59 + 8686883 = 8686942
101 + 8686841 = 8686942
113 + 8686829 = 8686942
239 + 8686703 = 8686942
263 + 8686679 = 8686942
281 + 8686661 = 8686942

Showing the first eight; more decompositions exist.
