Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635440, here are decompositions:

7 + 8635433 = 8635440
17 + 8635423 = 8635440
31 + 8635409 = 8635440
59 + 8635381 = 8635440
89 + 8635351 = 8635440
127 + 8635313 = 8635440
157 + 8635283 = 8635440
167 + 8635273 = 8635440

Showing the first eight; more decompositions exist.
