Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725868, here are decompositions:

37 + 8725831 = 8725868
199 + 8725669 = 8725868
211 + 8725657 = 8725868
241 + 8725627 = 8725868
337 + 8725531 = 8725868
379 + 8725489 = 8725868
409 + 8725459 = 8725868
439 + 8725429 = 8725868

Showing the first eight; more decompositions exist.
