Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609736, here are decompositions:

  • 13 + 31609723 = 31609736
  • 43 + 31609693 = 31609736
  • 127 + 31609609 = 31609736
  • 283 + 31609453 = 31609736
  • 397 + 31609339 = 31609736
  • 523 + 31609213 = 31609736
  • 547 + 31609189 = 31609736
  • 619 + 31609117 = 31609736

Showing the first eight; more decompositions exist.
