Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931806, here are decompositions:

  • 17 + 931789 = 931806
  • 23 + 931783 = 931806
  • 59 + 931747 = 931806
  • 67 + 931739 = 931806
  • 79 + 931727 = 931806
  • 97 + 931709 = 931806
  • 149 + 931657 = 931806
  • 167 + 931639 = 931806

Showing the first eight; more decompositions exist.
