Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725610, here are decompositions:

43 + 8725567 = 8725610
79 + 8725531 = 8725610
151 + 8725459 = 8725610
181 + 8725429 = 8725610
211 + 8725399 = 8725610
331 + 8725279 = 8725610
367 + 8725243 = 8725610
433 + 8725177 = 8725610

Showing the first eight; more decompositions exist.
