Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628894, here are decompositions:

5 + 8628889 = 8628894
11 + 8628883 = 8628894
37 + 8628857 = 8628894
47 + 8628847 = 8628894
83 + 8628811 = 8628894
103 + 8628791 = 8628894
107 + 8628787 = 8628894
167 + 8628727 = 8628894

Showing the first eight; more decompositions exist.
