Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664780, here are decompositions:

23 + 8664757 = 8664780
37 + 8664743 = 8664780
41 + 8664739 = 8664780
79 + 8664701 = 8664780
109 + 8664671 = 8664780
167 + 8664613 = 8664780
199 + 8664581 = 8664780
227 + 8664553 = 8664780

Showing the first eight; more decompositions exist.
