Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642206, here are decompositions:

17 + 8642189 = 8642206
47 + 8642159 = 8642206
59 + 8642147 = 8642206
107 + 8642099 = 8642206
149 + 8642057 = 8642206
173 + 8642033 = 8642206
179 + 8642027 = 8642206
257 + 8641949 = 8642206

Showing the first eight; more decompositions exist.
