Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554220, here are decompositions:

  • 19 + 33554201 = 33554220
  • 53 + 33554167 = 33554220
  • 61 + 33554159 = 33554220
  • 83 + 33554137 = 33554220
  • 97 + 33554123 = 33554220
  • 127 + 33554093 = 33554220
  • 137 + 33554083 = 33554220
  • 199 + 33554021 = 33554220

Showing the first eight; more decompositions exist.
