Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728564, here are decompositions:

83 + 8728481 = 8728564
107 + 8728457 = 8728564
137 + 8728427 = 8728564
167 + 8728397 = 8728564
191 + 8728373 = 8728564
233 + 8728331 = 8728564
353 + 8728211 = 8728564
491 + 8728073 = 8728564

Showing the first eight; more decompositions exist.
