Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728032, here are decompositions:

43 + 8727989 = 8728032
101 + 8727931 = 8728032
223 + 8727809 = 8728032
241 + 8727791 = 8728032
331 + 8727701 = 8728032
359 + 8727673 = 8728032
373 + 8727659 = 8728032
389 + 8727643 = 8728032

Showing the first eight; more decompositions exist.
