Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639804, here are decompositions:

7 + 8639797 = 8639804
31 + 8639773 = 8639804
157 + 8639647 = 8639804
241 + 8639563 = 8639804
457 + 8639347 = 8639804
541 + 8639263 = 8639804
577 + 8639227 = 8639804
643 + 8639161 = 8639804

Showing the first eight; more decompositions exist.
