Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728046, here are decompositions:

109 + 8727937 = 8728046
139 + 8727907 = 8728046
373 + 8727673 = 8728046
463 + 8727583 = 8728046
619 + 8727427 = 8728046
883 + 8727163 = 8728046
937 + 8727109 = 8728046
997 + 8727049 = 8728046

Showing the first eight; more decompositions exist.
