Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633780, here are decompositions:

3 + 8633777 = 8633780
13 + 8633767 = 8633780
61 + 8633719 = 8633780
79 + 8633701 = 8633780
97 + 8633683 = 8633780
139 + 8633641 = 8633780
229 + 8633551 = 8633780
349 + 8633431 = 8633780

Showing the first eight; more decompositions exist.
