Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725460, here are decompositions:

31 + 8725429 = 8725460
61 + 8725399 = 8725460
97 + 8725363 = 8725460
103 + 8725357 = 8725460
181 + 8725279 = 8725460
241 + 8725219 = 8725460
277 + 8725183 = 8725460
283 + 8725177 = 8725460

Showing the first eight; more decompositions exist.
