Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725424, here are decompositions:

3 + 8725421 = 8725424
61 + 8725363 = 8725424
67 + 8725357 = 8725424
181 + 8725243 = 8725424
241 + 8725183 = 8725424
271 + 8725153 = 8725424
277 + 8725147 = 8725424
283 + 8725141 = 8725424

Showing the first eight; more decompositions exist.
