Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630772, here are decompositions:

13 + 8630759 = 8630772
23 + 8630749 = 8630772
89 + 8630683 = 8630772
103 + 8630669 = 8630772
109 + 8630663 = 8630772
131 + 8630641 = 8630772
173 + 8630599 = 8630772
179 + 8630593 = 8630772

Showing the first eight; more decompositions exist.
