Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677868, here are decompositions:

97 + 8677771 = 8677868
109 + 8677759 = 8677868
571 + 8677297 = 8677868
601 + 8677267 = 8677868
607 + 8677261 = 8677868
811 + 8677057 = 8677868
877 + 8676991 = 8677868
919 + 8676949 = 8677868

Showing the first eight; more decompositions exist.
