Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725636, here are decompositions:

5 + 8725631 = 8725636
89 + 8725547 = 8725636
113 + 8725523 = 8725636
137 + 8725499 = 8725636
173 + 8725463 = 8725636
239 + 8725397 = 8725636
317 + 8725319 = 8725636
383 + 8725253 = 8725636

Showing the first eight; more decompositions exist.
