Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028732, here are decompositions:

151 + 1028581 = 1028732
163 + 1028569 = 1028732
223 + 1028509 = 1028732
541 + 1028191 = 1028732
619 + 1028113 = 1028732
631 + 1028101 = 1028732
643 + 1028089 = 1028732
709 + 1028023 = 1028732

Showing the first eight; more decompositions exist.
