Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526658, here are decompositions:

  • 11 + 31526647 = 31526658
  • 41 + 31526617 = 31526658
  • 131 + 31526527 = 31526658
  • 181 + 31526477 = 31526658
  • 227 + 31526431 = 31526658
  • 239 + 31526419 = 31526658
  • 269 + 31526389 = 31526658
  • 271 + 31526387 = 31526658

Showing the first eight; more decompositions exist.
