Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709258, here are decompositions:

29 + 8709229 = 8709258
37 + 8709221 = 8709258
67 + 8709191 = 8709258
71 + 8709187 = 8709258
109 + 8709149 = 8709258
137 + 8709121 = 8709258
179 + 8709079 = 8709258
191 + 8709067 = 8709258

Showing the first eight; more decompositions exist.
