Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677158, here are decompositions:

19 + 8677139 = 8677158
31 + 8677127 = 8677158
37 + 8677121 = 8677158
79 + 8677079 = 8677158
101 + 8677057 = 8677158
107 + 8677051 = 8677158
131 + 8677027 = 8677158
167 + 8676991 = 8677158

Showing the first eight; more decompositions exist.
