Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635438, here are decompositions:

5 + 8635433 = 8635438
29 + 8635409 = 8635438
179 + 8635259 = 8635438
197 + 8635241 = 8635438
239 + 8635199 = 8635438
389 + 8635049 = 8635438
467 + 8634971 = 8635438
491 + 8634947 = 8635438

Showing the first eight; more decompositions exist.
