Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668580, here are decompositions:

3 + 8668577 = 8668580
31 + 8668549 = 8668580
61 + 8668519 = 8668580
79 + 8668501 = 8668580
97 + 8668483 = 8668580
157 + 8668423 = 8668580
199 + 8668381 = 8668580
211 + 8668369 = 8668580

Showing the first eight; more decompositions exist.
