Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702172, here are decompositions:

13 + 8702159 = 8702172
23 + 8702149 = 8702172
41 + 8702131 = 8702172
79 + 8702093 = 8702172
109 + 8702063 = 8702172
163 + 8702009 = 8702172
173 + 8701999 = 8702172
181 + 8701991 = 8702172

Showing the first eight; more decompositions exist.
