Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628912, here are decompositions:

13 + 8628899 = 8628912
23 + 8628889 = 8628912
29 + 8628883 = 8628912
53 + 8628859 = 8628912
101 + 8628811 = 8628912
113 + 8628799 = 8628912
139 + 8628773 = 8628912
251 + 8628661 = 8628912

Showing the first eight; more decompositions exist.
