Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497710, here are decompositions:

  • 3 + 31497707 = 31497710
  • 31 + 31497679 = 31497710
  • 37 + 31497673 = 31497710
  • 43 + 31497667 = 31497710
  • 73 + 31497637 = 31497710
  • 109 + 31497601 = 31497710
  • 151 + 31497559 = 31497710
  • 163 + 31497547 = 31497710

Showing the first eight; more decompositions exist.
