Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635428, here are decompositions:

5 + 8635423 = 8635428
19 + 8635409 = 8635428
47 + 8635381 = 8635428
107 + 8635321 = 8635428
149 + 8635279 = 8635428
167 + 8635261 = 8635428
229 + 8635199 = 8635428
311 + 8635117 = 8635428

Showing the first eight; more decompositions exist.
