Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477632, here are decompositions:

  • 29 + 31477603 = 31477632
  • 61 + 31477571 = 31477632
  • 71 + 31477561 = 31477632
  • 79 + 31477553 = 31477632
  • 83 + 31477549 = 31477632
  • 89 + 31477543 = 31477632
  • 149 + 31477483 = 31477632
  • 233 + 31477399 = 31477632

Showing the first eight; more decompositions exist.
