Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728304, here are decompositions:

31 + 8728273 = 8728304
43 + 8728261 = 8728304
97 + 8728207 = 8728304
157 + 8728147 = 8728304
367 + 8727937 = 8728304
373 + 8727931 = 8728304
397 + 8727907 = 8728304
433 + 8727871 = 8728304

Showing the first eight; more decompositions exist.
