Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728298, here are decompositions:

37 + 8728261 = 8728298
151 + 8728147 = 8728298
367 + 8727931 = 8728298
541 + 8727757 = 8728298
571 + 8727727 = 8728298
769 + 8727529 = 8728298
1051 + 8727247 = 8728298
1087 + 8727211 = 8728298

Showing the first eight; more decompositions exist.
