Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698780, here are decompositions:

3 + 8698777 = 8698780
17 + 8698763 = 8698780
23 + 8698757 = 8698780
53 + 8698727 = 8698780
107 + 8698673 = 8698780
137 + 8698643 = 8698780
227 + 8698553 = 8698780
263 + 8698517 = 8698780

Showing the first eight; more decompositions exist.
