Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728446, here are decompositions:

19 + 8728427 = 8728446
59 + 8728387 = 8728446
73 + 8728373 = 8728446
137 + 8728309 = 8728446
157 + 8728289 = 8728446
173 + 8728273 = 8728446
239 + 8728207 = 8728446
277 + 8728169 = 8728446

Showing the first eight; more decompositions exist.
