Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556920, here are decompositions:

  • 17 + 33556903 = 33556920
  • 31 + 33556889 = 33556920
  • 41 + 33556879 = 33556920
  • 43 + 33556877 = 33556920
  • 53 + 33556867 = 33556920
  • 73 + 33556847 = 33556920
  • 79 + 33556841 = 33556920
  • 83 + 33556837 = 33556920

Showing the first eight; more decompositions exist.
