Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628980, here are decompositions:

7 + 8628973 = 8628980
13 + 8628967 = 8628980
43 + 8628937 = 8628980
67 + 8628913 = 8628980
97 + 8628883 = 8628980
181 + 8628799 = 8628980
193 + 8628787 = 8628980
229 + 8628751 = 8628980

Showing the first eight; more decompositions exist.
