Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660418, here are decompositions:

5 + 8660413 = 8660418
17 + 8660401 = 8660418
31 + 8660387 = 8660418
37 + 8660381 = 8660418
79 + 8660339 = 8660418
127 + 8660291 = 8660418
131 + 8660287 = 8660418
149 + 8660269 = 8660418

Showing the first eight; more decompositions exist.
