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.
