Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726160, here are decompositions:

17 + 8726143 = 8726160
19 + 8726141 = 8726160
59 + 8726101 = 8726160
67 + 8726093 = 8726160
73 + 8726087 = 8726160
97 + 8726063 = 8726160
109 + 8726051 = 8726160
139 + 8726021 = 8726160

Showing the first eight; more decompositions exist.
