Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660020, here are decompositions:

23 + 8659997 = 8660020
71 + 8659949 = 8660020
107 + 8659913 = 8660020
227 + 8659793 = 8660020
251 + 8659769 = 8660020
353 + 8659667 = 8660020
389 + 8659631 = 8660020
419 + 8659601 = 8660020

Showing the first eight; more decompositions exist.
