Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709222, here are decompositions:

31 + 8709191 = 8709222
73 + 8709149 = 8709222
83 + 8709139 = 8709222
89 + 8709133 = 8709222
101 + 8709121 = 8709222
163 + 8709059 = 8709222
251 + 8708971 = 8709222
311 + 8708911 = 8709222

Showing the first eight; more decompositions exist.
