Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543740, here are decompositions:

  • 31 + 33543709 = 33543740
  • 67 + 33543673 = 33543740
  • 79 + 33543661 = 33543740
  • 157 + 33543583 = 33543740
  • 163 + 33543577 = 33543740
  • 193 + 33543547 = 33543740
  • 211 + 33543529 = 33543740
  • 229 + 33543511 = 33543740

Showing the first eight; more decompositions exist.
