Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660490, here are decompositions:

23 + 8660467 = 8660490
29 + 8660461 = 8660490
53 + 8660437 = 8660490
67 + 8660423 = 8660490
71 + 8660419 = 8660490
89 + 8660401 = 8660490
103 + 8660387 = 8660490
107 + 8660383 = 8660490

Showing the first eight; more decompositions exist.
