Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635540, here are decompositions:

71 + 8635469 = 8635540
107 + 8635433 = 8635540
131 + 8635409 = 8635540
227 + 8635313 = 8635540
257 + 8635283 = 8635540
281 + 8635259 = 8635540
467 + 8635073 = 8635540
479 + 8635061 = 8635540

Showing the first eight; more decompositions exist.
