Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668280, here are decompositions:

7 + 8668273 = 8668280
13 + 8668267 = 8668280
73 + 8668207 = 8668280
79 + 8668201 = 8668280
139 + 8668141 = 8668280
199 + 8668081 = 8668280
223 + 8668057 = 8668280
307 + 8667973 = 8668280

Showing the first eight; more decompositions exist.
