Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728262, here are decompositions:

331 + 8727931 = 8728262
349 + 8727913 = 8728262
619 + 8727643 = 8728262
643 + 8727619 = 8728262
661 + 8727601 = 8728262
733 + 8727529 = 8728262
769 + 8727493 = 8728262
811 + 8727451 = 8728262

Showing the first eight; more decompositions exist.
