Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549464, here are decompositions:

  • 13 + 31549451 = 31549464
  • 53 + 31549411 = 31549464
  • 61 + 31549403 = 31549464
  • 73 + 31549391 = 31549464
  • 83 + 31549381 = 31549464
  • 127 + 31549337 = 31549464
  • 137 + 31549327 = 31549464
  • 223 + 31549241 = 31549464

Showing the first eight; more decompositions exist.
