Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660458, here are decompositions:

71 + 8660387 = 8660458
89 + 8660369 = 8660458
167 + 8660291 = 8660458
269 + 8660189 = 8660458
281 + 8660177 = 8660458
419 + 8660039 = 8660458
461 + 8659997 = 8660458
509 + 8659949 = 8660458

Showing the first eight; more decompositions exist.
