Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728482, here are decompositions:

11 + 8728471 = 8728482
101 + 8728381 = 8728482
109 + 8728373 = 8728482
151 + 8728331 = 8728482
173 + 8728309 = 8728482
179 + 8728303 = 8728482
193 + 8728289 = 8728482
241 + 8728241 = 8728482

Showing the first eight; more decompositions exist.
