Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497010, here are decompositions:

  • 3 + 31497007 = 31497010
  • 47 + 31496963 = 31497010
  • 53 + 31496957 = 31497010
  • 89 + 31496921 = 31497010
  • 137 + 31496873 = 31497010
  • 191 + 31496819 = 31497010
  • 227 + 31496783 = 31497010
  • 269 + 31496741 = 31497010

Showing the first eight; more decompositions exist.
