Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728558, here are decompositions:

101 + 8728457 = 8728558
131 + 8728427 = 8728558
227 + 8728331 = 8728558
269 + 8728289 = 8728558
317 + 8728241 = 8728558
347 + 8728211 = 8728558
389 + 8728169 = 8728558
479 + 8728079 = 8728558

Showing the first eight; more decompositions exist.
