Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544840, here are decompositions:

  • 29 + 33544811 = 33544840
  • 59 + 33544781 = 33544840
  • 101 + 33544739 = 33544840
  • 107 + 33544733 = 33544840
  • 137 + 33544703 = 33544840
  • 179 + 33544661 = 33544840
  • 227 + 33544613 = 33544840
  • 257 + 33544583 = 33544840

Showing the first eight; more decompositions exist.
