Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700178, here are decompositions:

17 + 8700161 = 8700178
107 + 8700071 = 8700178
131 + 8700047 = 8700178
167 + 8700011 = 8700178
197 + 8699981 = 8700178
659 + 8699519 = 8700178
677 + 8699501 = 8700178
797 + 8699381 = 8700178

Showing the first eight; more decompositions exist.
