Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518728, here are decompositions:

  • 59 + 33518669 = 33518728
  • 107 + 33518621 = 33518728
  • 137 + 33518591 = 33518728
  • 311 + 33518417 = 33518728
  • 401 + 33518327 = 33518728
  • 431 + 33518297 = 33518728
  • 461 + 33518267 = 33518728
  • 587 + 33518141 = 33518728

Showing the first eight; more decompositions exist.
