Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668520, here are decompositions:

19 + 8668501 = 8668520
31 + 8668489 = 8668520
37 + 8668483 = 8668520
61 + 8668459 = 8668520
97 + 8668423 = 8668520
139 + 8668381 = 8668520
151 + 8668369 = 8668520
163 + 8668357 = 8668520

Showing the first eight; more decompositions exist.
