Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669218, here are decompositions:

11 + 8669207 = 8669218
29 + 8669189 = 8669218
59 + 8669159 = 8669218
101 + 8669117 = 8669218
191 + 8669027 = 8669218
251 + 8668967 = 8669218
317 + 8668901 = 8669218
401 + 8668817 = 8669218

Showing the first eight; more decompositions exist.
