Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617772, here are decompositions:

3 + 8617769 = 8617772
19 + 8617753 = 8617772
73 + 8617699 = 8617772
211 + 8617561 = 8617772
223 + 8617549 = 8617772
439 + 8617333 = 8617772
571 + 8617201 = 8617772
601 + 8617171 = 8617772

Showing the first eight; more decompositions exist.
