Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018298, here are decompositions:

7 + 1018291 = 1018298
97 + 1018201 = 1018298
241 + 1018057 = 1018298
277 + 1018021 = 1018298
409 + 1017889 = 1018298
439 + 1017859 = 1018298
499 + 1017799 = 1018298
577 + 1017721 = 1018298

Showing the first eight; more decompositions exist.
