Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677940, here are decompositions:

181 + 8677759 = 8677940
277 + 8677663 = 8677940
457 + 8677483 = 8677940
463 + 8677477 = 8677940
487 + 8677453 = 8677940
541 + 8677399 = 8677940
547 + 8677393 = 8677940
643 + 8677297 = 8677940

Showing the first eight; more decompositions exist.
