Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736638, here are decompositions:

7 + 8736631 = 8736638
109 + 8736529 = 8736638
271 + 8736367 = 8736638
439 + 8736199 = 8736638
499 + 8736139 = 8736638
541 + 8736097 = 8736638
577 + 8736061 = 8736638
601 + 8736037 = 8736638

Showing the first eight; more decompositions exist.
