Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668532, here are decompositions:

13 + 8668519 = 8668532
31 + 8668501 = 8668532
43 + 8668489 = 8668532
73 + 8668459 = 8668532
109 + 8668423 = 8668532
151 + 8668381 = 8668532
163 + 8668369 = 8668532
331 + 8668201 = 8668532

Showing the first eight; more decompositions exist.
