Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738666, here are decompositions:

7 + 8738659 = 8738666
127 + 8738539 = 8738666
193 + 8738473 = 8738666
229 + 8738437 = 8738666
283 + 8738383 = 8738666
367 + 8738299 = 8738666
373 + 8738293 = 8738666
439 + 8738227 = 8738666

Showing the first eight; more decompositions exist.
