Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534832, here are decompositions:

  • 13 + 31534819 = 31534832
  • 31 + 31534801 = 31534832
  • 79 + 31534753 = 31534832
  • 103 + 31534729 = 31534832
  • 163 + 31534669 = 31534832
  • 181 + 31534651 = 31534832
  • 271 + 31534561 = 31534832
  • 331 + 31534501 = 31534832

Showing the first eight; more decompositions exist.
