Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616772, here are decompositions:

11 + 8616761 = 8616772
53 + 8616719 = 8616772
83 + 8616689 = 8616772
173 + 8616599 = 8616772
239 + 8616533 = 8616772
401 + 8616371 = 8616772
419 + 8616353 = 8616772
449 + 8616323 = 8616772

Showing the first eight; more decompositions exist.
