Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660474, here are decompositions:

7 + 8660467 = 8660474
13 + 8660461 = 8660474
37 + 8660437 = 8660474
61 + 8660413 = 8660474
73 + 8660401 = 8660474
211 + 8660263 = 8660474
241 + 8660233 = 8660474
271 + 8660203 = 8660474

Showing the first eight; more decompositions exist.
