Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608780, here are decompositions:

3 + 8608777 = 8608780
29 + 8608751 = 8608780
53 + 8608727 = 8608780
107 + 8608673 = 8608780
113 + 8608667 = 8608780
197 + 8608583 = 8608780
227 + 8608553 = 8608780
251 + 8608529 = 8608780

Showing the first eight; more decompositions exist.
