Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725910, here are decompositions:

79 + 8725831 = 8725910
97 + 8725813 = 8725910
211 + 8725699 = 8725910
229 + 8725681 = 8725910
241 + 8725669 = 8725910
283 + 8725627 = 8725910
379 + 8725531 = 8725910
421 + 8725489 = 8725910

Showing the first eight; more decompositions exist.
