Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542128, here are decompositions:

  • 17 + 33542111 = 33542128
  • 131 + 33541997 = 33542128
  • 149 + 33541979 = 33542128
  • 197 + 33541931 = 33542128
  • 311 + 33541817 = 33542128
  • 359 + 33541769 = 33542128
  • 419 + 33541709 = 33542128
  • 461 + 33541667 = 33542128

Showing the first eight; more decompositions exist.
