Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662638, here are decompositions:

41 + 8662597 = 8662638
59 + 8662579 = 8662638
97 + 8662541 = 8662638
107 + 8662531 = 8662638
151 + 8662487 = 8662638
157 + 8662481 = 8662638
167 + 8662471 = 8662638
191 + 8662447 = 8662638

Showing the first eight; more decompositions exist.
