Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677864, here are decompositions:

17 + 8677847 = 8677864
23 + 8677841 = 8677864
101 + 8677763 = 8677864
137 + 8677727 = 8677864
257 + 8677607 = 8677864
311 + 8677553 = 8677864
353 + 8677511 = 8677864
383 + 8677481 = 8677864

Showing the first eight; more decompositions exist.
