Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728250, here are decompositions:

43 + 8728207 = 8728250
103 + 8728147 = 8728250
313 + 8727937 = 8728250
337 + 8727913 = 8728250
379 + 8727871 = 8728250
523 + 8727727 = 8728250
577 + 8727673 = 8728250
607 + 8727643 = 8728250

Showing the first eight; more decompositions exist.
