Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726170, here are decompositions:

29 + 8726141 = 8726170
83 + 8726087 = 8726170
107 + 8726063 = 8726170
149 + 8726021 = 8726170
179 + 8725991 = 8726170
191 + 8725979 = 8726170
239 + 8725931 = 8726170
293 + 8725877 = 8726170

Showing the first eight; more decompositions exist.
