Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744666, here are decompositions:

3 + 8744663 = 8744666
67 + 8744599 = 8744666
103 + 8744563 = 8744666
109 + 8744557 = 8744666
199 + 8744467 = 8744666
349 + 8744317 = 8744666
397 + 8744269 = 8744666
433 + 8744233 = 8744666

Showing the first eight; more decompositions exist.
