Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608778, here are decompositions:

7 + 8608771 = 8608778
19 + 8608759 = 8608778
151 + 8608627 = 8608778
181 + 8608597 = 8608778
229 + 8608549 = 8608778
271 + 8608507 = 8608778
349 + 8608429 = 8608778
379 + 8608399 = 8608778

Showing the first eight; more decompositions exist.
