Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668748, here are decompositions:

7 + 8668741 = 8668748
37 + 8668711 = 8668748
61 + 8668687 = 8668748
139 + 8668609 = 8668748
199 + 8668549 = 8668748
229 + 8668519 = 8668748
367 + 8668381 = 8668748
379 + 8668369 = 8668748

Showing the first eight; more decompositions exist.
