Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534784, here are decompositions:

  • 31 + 31534753 = 31534784
  • 223 + 31534561 = 31534784
  • 241 + 31534543 = 31534784
  • 283 + 31534501 = 31534784
  • 373 + 31534411 = 31534784
  • 487 + 31534297 = 31534784
  • 601 + 31534183 = 31534784
  • 643 + 31534141 = 31534784

Showing the first eight; more decompositions exist.
