Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488840, here are decompositions:

  • 3 + 33488837 = 33488840
  • 61 + 33488779 = 33488840
  • 157 + 33488683 = 33488840
  • 193 + 33488647 = 33488840
  • 241 + 33488599 = 33488840
  • 271 + 33488569 = 33488840
  • 283 + 33488557 = 33488840
  • 331 + 33488509 = 33488840

Showing the first eight; more decompositions exist.
