Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668742, here are decompositions:

3 + 8668739 = 8668742
31 + 8668711 = 8668742
193 + 8668549 = 8668742
223 + 8668519 = 8668742
241 + 8668501 = 8668742
283 + 8668459 = 8668742
373 + 8668369 = 8668742
463 + 8668279 = 8668742

Showing the first eight; more decompositions exist.
