Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518100, here are decompositions:

  • 19 + 33518081 = 33518100
  • 53 + 33518047 = 33518100
  • 71 + 33518029 = 33518100
  • 79 + 33518021 = 33518100
  • 89 + 33518011 = 33518100
  • 113 + 33517987 = 33518100
  • 157 + 33517943 = 33518100
  • 179 + 33517921 = 33518100

Showing the first eight; more decompositions exist.
