Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526790, here are decompositions:

  • 13 + 31526777 = 31526790
  • 17 + 31526773 = 31526790
  • 19 + 31526771 = 31526790
  • 37 + 31526753 = 31526790
  • 41 + 31526749 = 31526790
  • 59 + 31526731 = 31526790
  • 67 + 31526723 = 31526790
  • 101 + 31526689 = 31526790

Showing the first eight; more decompositions exist.
