Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659986, here are decompositions:

29 + 8659957 = 8659986
37 + 8659949 = 8659986
47 + 8659939 = 8659986
59 + 8659927 = 8659986
73 + 8659913 = 8659986
113 + 8659873 = 8659986
149 + 8659837 = 8659986
193 + 8659793 = 8659986

Showing the first eight; more decompositions exist.
