Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709166, here are decompositions:

17 + 8709149 = 8709166
107 + 8709059 = 8709166
197 + 8708969 = 8709166
317 + 8708849 = 8709166
359 + 8708807 = 8709166
449 + 8708717 = 8709166
503 + 8708663 = 8709166
509 + 8708657 = 8709166

Showing the first eight; more decompositions exist.
