Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701180, here are decompositions:

3 + 8701177 = 8701180
17 + 8701163 = 8701180
113 + 8701067 = 8701180
167 + 8701013 = 8701180
179 + 8701001 = 8701180
227 + 8700953 = 8701180
233 + 8700947 = 8701180
239 + 8700941 = 8701180

Showing the first eight; more decompositions exist.
