Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628918, here are decompositions:

5 + 8628913 = 8628918
19 + 8628899 = 8628918
29 + 8628889 = 8628918
59 + 8628859 = 8628918
61 + 8628857 = 8628918
71 + 8628847 = 8628918
107 + 8628811 = 8628918
127 + 8628791 = 8628918

Showing the first eight; more decompositions exist.
