Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725430, here are decompositions:

31 + 8725399 = 8725430
67 + 8725363 = 8725430
73 + 8725357 = 8725430
151 + 8725279 = 8725430
211 + 8725219 = 8725430
223 + 8725207 = 8725430
271 + 8725159 = 8725430
277 + 8725153 = 8725430

Showing the first eight; more decompositions exist.
