Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660444, here are decompositions:

7 + 8660437 = 8660444
31 + 8660413 = 8660444
43 + 8660401 = 8660444
61 + 8660383 = 8660444
157 + 8660287 = 8660444
181 + 8660263 = 8660444
211 + 8660233 = 8660444
223 + 8660221 = 8660444

Showing the first eight; more decompositions exist.
