Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736208, here are decompositions:

17 + 8736191 = 8736208
29 + 8736179 = 8736208
149 + 8736059 = 8736208
167 + 8736041 = 8736208
311 + 8735897 = 8736208
317 + 8735891 = 8736208
347 + 8735861 = 8736208
359 + 8735849 = 8736208

Showing the first eight; more decompositions exist.
