Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728326, here are decompositions:

17 + 8728309 = 8728326
23 + 8728303 = 8728326
37 + 8728289 = 8728326
53 + 8728273 = 8728326
157 + 8728169 = 8728326
179 + 8728147 = 8728326
197 + 8728129 = 8728326
337 + 8727989 = 8728326

Showing the first eight; more decompositions exist.
