Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687178, here are decompositions:

7 + 8687171 = 8687178
29 + 8687149 = 8687178
37 + 8687141 = 8687178
47 + 8687131 = 8687178
61 + 8687117 = 8687178
89 + 8687089 = 8687178
109 + 8687069 = 8687178
151 + 8687027 = 8687178

Showing the first eight; more decompositions exist.
