Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628564, here are decompositions:

11 + 8628553 = 8628564
13 + 8628551 = 8628564
17 + 8628547 = 8628564
71 + 8628493 = 8628564
83 + 8628481 = 8628564
101 + 8628463 = 8628564
157 + 8628407 = 8628564
181 + 8628383 = 8628564

Showing the first eight; more decompositions exist.
