Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728342, here are decompositions:

11 + 8728331 = 8728342
53 + 8728289 = 8728342
101 + 8728241 = 8728342
131 + 8728211 = 8728342
149 + 8728193 = 8728342
173 + 8728169 = 8728342
263 + 8728079 = 8728342
269 + 8728073 = 8728342

Showing the first eight; more decompositions exist.
