Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642298, here are decompositions:

17 + 8642281 = 8642298
61 + 8642237 = 8642298
101 + 8642197 = 8642298
109 + 8642189 = 8642298
139 + 8642159 = 8642298
151 + 8642147 = 8642298
157 + 8642141 = 8642298
179 + 8642119 = 8642298

Showing the first eight; more decompositions exist.
