Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728010, here are decompositions:

73 + 8727937 = 8728010
79 + 8727931 = 8728010
97 + 8727913 = 8728010
103 + 8727907 = 8728010
139 + 8727871 = 8728010
283 + 8727727 = 8728010
337 + 8727673 = 8728010
367 + 8727643 = 8728010

Showing the first eight; more decompositions exist.
