Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667986, here are decompositions:

7 + 8667979 = 8667986
13 + 8667973 = 8667986
37 + 8667949 = 8667986
73 + 8667913 = 8667986
79 + 8667907 = 8667986
139 + 8667847 = 8667986
157 + 8667829 = 8667986
193 + 8667793 = 8667986

Showing the first eight; more decompositions exist.
