Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725490, here are decompositions:

31 + 8725459 = 8725490
61 + 8725429 = 8725490
127 + 8725363 = 8725490
211 + 8725279 = 8725490
271 + 8725219 = 8725490
283 + 8725207 = 8725490
307 + 8725183 = 8725490
313 + 8725177 = 8725490

Showing the first eight; more decompositions exist.
