Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728274, here are decompositions:

13 + 8728261 = 8728274
67 + 8728207 = 8728274
127 + 8728147 = 8728274
337 + 8727937 = 8728274
367 + 8727907 = 8728274
547 + 8727727 = 8728274
601 + 8727673 = 8728274
631 + 8727643 = 8728274

Showing the first eight; more decompositions exist.
