Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491600, here are decompositions:

  • 7 + 33491593 = 33491600
  • 31 + 33491569 = 33491600
  • 67 + 33491533 = 33491600
  • 139 + 33491461 = 33491600
  • 229 + 33491371 = 33491600
  • 367 + 33491233 = 33491600
  • 379 + 33491221 = 33491600
  • 397 + 33491203 = 33491600

Showing the first eight; more decompositions exist.
