Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680772, here are decompositions:

3 + 8680769 = 8680772
19 + 8680753 = 8680772
31 + 8680741 = 8680772
73 + 8680699 = 8680772
103 + 8680669 = 8680772
229 + 8680543 = 8680772
271 + 8680501 = 8680772
523 + 8680249 = 8680772

Showing the first eight; more decompositions exist.
