Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722298, here are decompositions:

7 + 8722291 = 8722298
61 + 8722237 = 8722298
127 + 8722171 = 8722298
181 + 8722117 = 8722298
199 + 8722099 = 8722298
271 + 8722027 = 8722298
421 + 8721877 = 8722298
631 + 8721667 = 8722298

Showing the first eight; more decompositions exist.
