Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596842, here are decompositions:

  • 3 + 31596839 = 31596842
  • 73 + 31596769 = 31596842
  • 163 + 31596679 = 31596842
  • 181 + 31596661 = 31596842
  • 229 + 31596613 = 31596842
  • 271 + 31596571 = 31596842
  • 331 + 31596511 = 31596842
  • 439 + 31596403 = 31596842

Showing the first eight; more decompositions exist.
