Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728002, here are decompositions:

13 + 8727989 = 8728002
71 + 8727931 = 8728002
89 + 8727913 = 8728002
103 + 8727899 = 8728002
131 + 8727871 = 8728002
193 + 8727809 = 8728002
211 + 8727791 = 8728002
223 + 8727779 = 8728002

Showing the first eight; more decompositions exist.
