Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630726, here are decompositions:

43 + 8630683 = 8630726
73 + 8630653 = 8630726
79 + 8630647 = 8630726
127 + 8630599 = 8630726
277 + 8630449 = 8630726
283 + 8630443 = 8630726
457 + 8630269 = 8630726
487 + 8630239 = 8630726

Showing the first eight; more decompositions exist.
