Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642986, here are decompositions:

47 + 8642939 = 8642986
59 + 8642927 = 8642986
83 + 8642903 = 8642986
89 + 8642897 = 8642986
137 + 8642849 = 8642986
167 + 8642819 = 8642986
239 + 8642747 = 8642986
263 + 8642723 = 8642986

Showing the first eight; more decompositions exist.
