Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670800, here are decompositions:

97 + 8670703 = 8670800
163 + 8670637 = 8670800
181 + 8670619 = 8670800
211 + 8670589 = 8670800
241 + 8670559 = 8670800
277 + 8670523 = 8670800
349 + 8670451 = 8670800
367 + 8670433 = 8670800

Showing the first eight; more decompositions exist.
