Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668610, here are decompositions:

61 + 8668549 = 8668610
109 + 8668501 = 8668610
127 + 8668483 = 8668610
151 + 8668459 = 8668610
229 + 8668381 = 8668610
241 + 8668369 = 8668610
331 + 8668279 = 8668610
337 + 8668273 = 8668610

Showing the first eight; more decompositions exist.
