Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606780, here are decompositions:

43 + 8606737 = 8606780
181 + 8606599 = 8606780
223 + 8606557 = 8606780
271 + 8606509 = 8606780
337 + 8606443 = 8606780
349 + 8606431 = 8606780
367 + 8606413 = 8606780
379 + 8606401 = 8606780

Showing the first eight; more decompositions exist.
