Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627006, here are decompositions:

  • 29 + 31626977 = 31627006
  • 107 + 31626899 = 31627006
  • 113 + 31626893 = 31627006
  • 137 + 31626869 = 31627006
  • 149 + 31626857 = 31627006
  • 167 + 31626839 = 31627006
  • 179 + 31626827 = 31627006
  • 239 + 31626767 = 31627006

Showing the first eight; more decompositions exist.
