Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542440, here are decompositions:

  • 101 + 33542339 = 33542440
  • 179 + 33542261 = 33542440
  • 251 + 33542189 = 33542440
  • 293 + 33542147 = 33542440
  • 389 + 33542051 = 33542440
  • 443 + 33541997 = 33542440
  • 461 + 33541979 = 33542440
  • 509 + 33541931 = 33542440

Showing the first eight; more decompositions exist.
