Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609558, here are decompositions:

  • 11 + 31609547 = 31609558
  • 17 + 31609541 = 31609558
  • 59 + 31609499 = 31609558
  • 89 + 31609469 = 31609558
  • 107 + 31609451 = 31609558
  • 269 + 31609289 = 31609558
  • 467 + 31609091 = 31609558
  • 479 + 31609079 = 31609558

Showing the first eight; more decompositions exist.
