Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677840, here are decompositions:

11 + 8677829 = 8677840
113 + 8677727 = 8677840
233 + 8677607 = 8677840
263 + 8677577 = 8677840
359 + 8677481 = 8677840
383 + 8677457 = 8677840
443 + 8677397 = 8677840
449 + 8677391 = 8677840

Showing the first eight; more decompositions exist.
