Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728882, here are decompositions:

59 + 8728823 = 8728882
191 + 8728691 = 8728882
233 + 8728649 = 8728882
311 + 8728571 = 8728882
401 + 8728481 = 8728882
509 + 8728373 = 8728882
593 + 8728289 = 8728882
641 + 8728241 = 8728882

Showing the first eight; more decompositions exist.
