Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669826, here are decompositions:

5 + 8669821 = 8669826
59 + 8669767 = 8669826
157 + 8669669 = 8669826
197 + 8669629 = 8669826
199 + 8669627 = 8669826
233 + 8669593 = 8669826
283 + 8669543 = 8669826
313 + 8669513 = 8669826

Showing the first eight; more decompositions exist.
