Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618298, here are decompositions:

5 + 8618293 = 8618298
11 + 8618287 = 8618298
41 + 8618257 = 8618298
47 + 8618251 = 8618298
61 + 8618237 = 8618298
149 + 8618149 = 8618298
151 + 8618147 = 8618298
167 + 8618131 = 8618298

Showing the first eight; more decompositions exist.
