Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725622, here are decompositions:

13 + 8725609 = 8725622
163 + 8725459 = 8725622
193 + 8725429 = 8725622
223 + 8725399 = 8725622
379 + 8725243 = 8725622
439 + 8725183 = 8725622
463 + 8725159 = 8725622
523 + 8725099 = 8725622

Showing the first eight; more decompositions exist.
