Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677980, here are decompositions:

13 + 8677967 = 8677980
19 + 8677961 = 8677980
29 + 8677951 = 8677980
89 + 8677891 = 8677980
97 + 8677883 = 8677980
139 + 8677841 = 8677980
151 + 8677829 = 8677980
257 + 8677723 = 8677980

Showing the first eight; more decompositions exist.
