Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728432, here are decompositions:

5 + 8728427 = 8728432
59 + 8728373 = 8728432
101 + 8728331 = 8728432
191 + 8728241 = 8728432
239 + 8728193 = 8728432
263 + 8728169 = 8728432
353 + 8728079 = 8728432
359 + 8728073 = 8728432

Showing the first eight; more decompositions exist.
