Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622638, here are decompositions:

61 + 8622577 = 8622638
109 + 8622529 = 8622638
127 + 8622511 = 8622638
139 + 8622499 = 8622638
151 + 8622487 = 8622638
307 + 8622331 = 8622638
331 + 8622307 = 8622638
337 + 8622301 = 8622638

Showing the first eight; more decompositions exist.
