Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677880, here are decompositions:

109 + 8677771 = 8677880
157 + 8677723 = 8677880
199 + 8677681 = 8677880
229 + 8677651 = 8677880
397 + 8677483 = 8677880
487 + 8677393 = 8677880
613 + 8677267 = 8677880
619 + 8677261 = 8677880

Showing the first eight; more decompositions exist.
