Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668490, here are decompositions:

7 + 8668483 = 8668490
31 + 8668459 = 8668490
67 + 8668423 = 8668490
109 + 8668381 = 8668490
211 + 8668279 = 8668490
223 + 8668267 = 8668490
283 + 8668207 = 8668490
349 + 8668141 = 8668490

Showing the first eight; more decompositions exist.
