Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728544, here are decompositions:

31 + 8728513 = 8728544
61 + 8728483 = 8728544
73 + 8728471 = 8728544
157 + 8728387 = 8728544
163 + 8728381 = 8728544
241 + 8728303 = 8728544
271 + 8728273 = 8728544
283 + 8728261 = 8728544

Showing the first eight; more decompositions exist.
