Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709486, here are decompositions:

17 + 8709469 = 8709486
43 + 8709443 = 8709486
103 + 8709383 = 8709486
109 + 8709377 = 8709486
113 + 8709373 = 8709486
173 + 8709313 = 8709486
197 + 8709289 = 8709486
229 + 8709257 = 8709486

Showing the first eight; more decompositions exist.
