Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668424, here are decompositions:

3 + 8668421 = 8668424
43 + 8668381 = 8668424
67 + 8668357 = 8668424
151 + 8668273 = 8668424
157 + 8668267 = 8668424
223 + 8668201 = 8668424
283 + 8668141 = 8668424
313 + 8668111 = 8668424

Showing the first eight; more decompositions exist.
