Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728168, here are decompositions:

89 + 8728079 = 8728168
131 + 8728037 = 8728168
179 + 8727989 = 8728168
269 + 8727899 = 8728168
311 + 8727857 = 8728168
359 + 8727809 = 8728168
389 + 8727779 = 8728168
401 + 8727767 = 8728168

Showing the first eight; more decompositions exist.
