Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638662, here are decompositions:

29 + 8638633 = 8638662
41 + 8638621 = 8638662
79 + 8638583 = 8638662
181 + 8638481 = 8638662
191 + 8638471 = 8638662
199 + 8638463 = 8638662
211 + 8638451 = 8638662
251 + 8638411 = 8638662

Showing the first eight; more decompositions exist.
