Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666462, here are decompositions:

3 + 8666459 = 8666462
19 + 8666443 = 8666462
31 + 8666431 = 8666462
43 + 8666419 = 8666462
139 + 8666323 = 8666462
193 + 8666269 = 8666462
439 + 8666023 = 8666462
463 + 8665999 = 8666462

Showing the first eight; more decompositions exist.
