Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581100, here are decompositions:

  • 13 + 33581087 = 33581100
  • 73 + 33581027 = 33581100
  • 79 + 33581021 = 33581100
  • 89 + 33581011 = 33581100
  • 107 + 33580993 = 33581100
  • 109 + 33580991 = 33581100
  • 181 + 33580919 = 33581100
  • 191 + 33580909 = 33581100

Showing the first eight; more decompositions exist.
