Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728462, here are decompositions:

5 + 8728457 = 8728462
89 + 8728373 = 8728462
131 + 8728331 = 8728462
173 + 8728289 = 8728462
251 + 8728211 = 8728462
269 + 8728193 = 8728462
293 + 8728169 = 8728462
383 + 8728079 = 8728462

Showing the first eight; more decompositions exist.
