Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628842, here are decompositions:

31 + 8628811 = 8628842
43 + 8628799 = 8628842
181 + 8628661 = 8628842
199 + 8628643 = 8628842
241 + 8628601 = 8628842
349 + 8628493 = 8628842
379 + 8628463 = 8628842
421 + 8628421 = 8628842

Showing the first eight; more decompositions exist.
