Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755986, here are decompositions:

13 + 8755973 = 8755986
23 + 8755963 = 8755986
73 + 8755913 = 8755986
97 + 8755889 = 8755986
137 + 8755849 = 8755986
163 + 8755823 = 8755986
167 + 8755819 = 8755986
257 + 8755729 = 8755986

Showing the first eight; more decompositions exist.
