Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660398, here are decompositions:

11 + 8660387 = 8660398
17 + 8660381 = 8660398
29 + 8660369 = 8660398
59 + 8660339 = 8660398
101 + 8660297 = 8660398
107 + 8660291 = 8660398
311 + 8660087 = 8660398
317 + 8660081 = 8660398

Showing the first eight; more decompositions exist.
