Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515840, here are decompositions:

  • 3 + 33515837 = 33515840
  • 37 + 33515803 = 33515840
  • 67 + 33515773 = 33515840
  • 139 + 33515701 = 33515840
  • 223 + 33515617 = 33515840
  • 271 + 33515569 = 33515840
  • 331 + 33515509 = 33515840
  • 367 + 33515473 = 33515840

Showing the first eight; more decompositions exist.
