Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725550, here are decompositions:

3 + 8725547 = 8725550
19 + 8725531 = 8725550
61 + 8725489 = 8725550
151 + 8725399 = 8725550
193 + 8725357 = 8725550
271 + 8725279 = 8725550
307 + 8725243 = 8725550
331 + 8725219 = 8725550

Showing the first eight; more decompositions exist.
