Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629028, here are decompositions:

19 + 8629009 = 8629028
61 + 8628967 = 8629028
139 + 8628889 = 8629028
181 + 8628847 = 8629028
229 + 8628799 = 8629028
241 + 8628787 = 8629028
277 + 8628751 = 8629028
367 + 8628661 = 8629028

Showing the first eight; more decompositions exist.
