Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728206, here are decompositions:

13 + 8728193 = 8728206
37 + 8728169 = 8728206
59 + 8728147 = 8728206
127 + 8728079 = 8728206
269 + 8727937 = 8728206
293 + 8727913 = 8728206
307 + 8727899 = 8728206
349 + 8727857 = 8728206

Showing the first eight; more decompositions exist.
