Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670836, here are decompositions:

127 + 8670709 = 8670836
157 + 8670679 = 8670836
199 + 8670637 = 8670836
277 + 8670559 = 8670836
283 + 8670553 = 8670836
313 + 8670523 = 8670836
337 + 8670499 = 8670836
439 + 8670397 = 8670836

Showing the first eight; more decompositions exist.
