Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728534, here are decompositions:

53 + 8728481 = 8728534
107 + 8728427 = 8728534
137 + 8728397 = 8728534
293 + 8728241 = 8728534
461 + 8728073 = 8728534
677 + 8727857 = 8728534
743 + 8727791 = 8728534
761 + 8727773 = 8728534

Showing the first eight; more decompositions exist.
