Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638298, here are decompositions:

7 + 8638291 = 8638298
61 + 8638237 = 8638298
79 + 8638219 = 8638298
181 + 8638117 = 8638298
307 + 8637991 = 8638298
601 + 8637697 = 8638298
631 + 8637667 = 8638298
661 + 8637637 = 8638298

Showing the first eight; more decompositions exist.
