Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728506, here are decompositions:

23 + 8728483 = 8728506
79 + 8728427 = 8728506
109 + 8728397 = 8728506
197 + 8728309 = 8728506
233 + 8728273 = 8728506
313 + 8728193 = 8728506
337 + 8728169 = 8728506
359 + 8728147 = 8728506

Showing the first eight; more decompositions exist.
