Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726158, here are decompositions:

17 + 8726141 = 8726158
71 + 8726087 = 8726158
107 + 8726051 = 8726158
131 + 8726027 = 8726158
137 + 8726021 = 8726158
167 + 8725991 = 8726158
179 + 8725979 = 8726158
197 + 8725961 = 8726158

Showing the first eight; more decompositions exist.
