Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677178, here are decompositions:

7 + 8677171 = 8677178
127 + 8677051 = 8677178
151 + 8677027 = 8677178
229 + 8676949 = 8677178
241 + 8676937 = 8677178
331 + 8676847 = 8677178
379 + 8676799 = 8677178
397 + 8676781 = 8677178

Showing the first eight; more decompositions exist.
