Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709162, here are decompositions:

13 + 8709149 = 8709162
23 + 8709139 = 8709162
29 + 8709133 = 8709162
41 + 8709121 = 8709162
83 + 8709079 = 8709162
103 + 8709059 = 8709162
191 + 8708971 = 8709162
193 + 8708969 = 8709162

Showing the first eight; more decompositions exist.
