Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759172, here are decompositions:

5 + 8759167 = 8759172
11 + 8759161 = 8759172
31 + 8759141 = 8759172
83 + 8759089 = 8759172
113 + 8759059 = 8759172
139 + 8759033 = 8759172
179 + 8758993 = 8759172
193 + 8758979 = 8759172

Showing the first eight; more decompositions exist.
