Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660638, here are decompositions:

29 + 8660609 = 8660638
59 + 8660579 = 8660638
101 + 8660537 = 8660638
131 + 8660507 = 8660638
251 + 8660387 = 8660638
257 + 8660381 = 8660638
269 + 8660369 = 8660638
347 + 8660291 = 8660638

Showing the first eight; more decompositions exist.
