Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631298, here are decompositions:

29 + 8631269 = 8631298
47 + 8631251 = 8631298
107 + 8631191 = 8631298
131 + 8631167 = 8631298
257 + 8631041 = 8631298
281 + 8631017 = 8631298
461 + 8630837 = 8631298
509 + 8630789 = 8631298

Showing the first eight; more decompositions exist.
