Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660506, here are decompositions:

3 + 8660503 = 8660506
83 + 8660423 = 8660506
137 + 8660369 = 8660506
167 + 8660339 = 8660506
317 + 8660189 = 8660506
419 + 8660087 = 8660506
467 + 8660039 = 8660506
509 + 8659997 = 8660506

Showing the first eight; more decompositions exist.
