Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677520, here are decompositions:

37 + 8677483 = 8677520
43 + 8677477 = 8677520
67 + 8677453 = 8677520
127 + 8677393 = 8677520
223 + 8677297 = 8677520
349 + 8677171 = 8677520
463 + 8677057 = 8677520
547 + 8676973 = 8677520

Showing the first eight; more decompositions exist.
