Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709216, here are decompositions:

29 + 8709187 = 8709216
67 + 8709149 = 8709216
83 + 8709133 = 8709216
137 + 8709079 = 8709216
149 + 8709067 = 8709216
157 + 8709059 = 8709216
367 + 8708849 = 8709216
409 + 8708807 = 8709216

Showing the first eight; more decompositions exist.
