Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725586, here are decompositions:

19 + 8725567 = 8725586
97 + 8725489 = 8725586
127 + 8725459 = 8725586
157 + 8725429 = 8725586
223 + 8725363 = 8725586
229 + 8725357 = 8725586
307 + 8725279 = 8725586
367 + 8725219 = 8725586

Showing the first eight; more decompositions exist.
