Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671360, here are decompositions:

29 + 8671331 = 8671360
53 + 8671307 = 8671360
167 + 8671193 = 8671360
227 + 8671133 = 8671360
233 + 8671127 = 8671360
263 + 8671097 = 8671360
293 + 8671067 = 8671360
353 + 8671007 = 8671360

Showing the first eight; more decompositions exist.
