Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725646, here are decompositions:

3 + 8725643 = 8725646
19 + 8725627 = 8725646
37 + 8725609 = 8725646
79 + 8725567 = 8725646
157 + 8725489 = 8725646
283 + 8725363 = 8725646
367 + 8725279 = 8725646
439 + 8725207 = 8725646

Showing the first eight; more decompositions exist.
