Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677870, here are decompositions:

23 + 8677847 = 8677870
29 + 8677841 = 8677870
41 + 8677829 = 8677870
107 + 8677763 = 8677870
263 + 8677607 = 8677870
293 + 8677577 = 8677870
317 + 8677553 = 8677870
359 + 8677511 = 8677870

Showing the first eight; more decompositions exist.
