Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628986, here are decompositions:

13 + 8628973 = 8628986
19 + 8628967 = 8628986
73 + 8628913 = 8628986
97 + 8628889 = 8628986
103 + 8628883 = 8628986
127 + 8628859 = 8628986
139 + 8628847 = 8628986
199 + 8628787 = 8628986

Showing the first eight; more decompositions exist.
