Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709138, here are decompositions:

5 + 8709133 = 8709138
17 + 8709121 = 8709138
59 + 8709079 = 8709138
71 + 8709067 = 8709138
79 + 8709059 = 8709138
131 + 8709007 = 8709138
167 + 8708971 = 8709138
227 + 8708911 = 8709138

Showing the first eight; more decompositions exist.
