Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726166, here are decompositions:

23 + 8726143 = 8726166
73 + 8726093 = 8726166
79 + 8726087 = 8726166
103 + 8726063 = 8726166
139 + 8726027 = 8726166
149 + 8726017 = 8726166
167 + 8725999 = 8726166
179 + 8725987 = 8726166

Showing the first eight; more decompositions exist.
