Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538922, here are decompositions:

  • 179 + 31538743 = 31538922
  • 193 + 31538729 = 31538922
  • 211 + 31538711 = 31538922
  • 229 + 31538693 = 31538922
  • 251 + 31538671 = 31538922
  • 269 + 31538653 = 31538922
  • 281 + 31538641 = 31538922
  • 293 + 31538629 = 31538922

Showing the first eight; more decompositions exist.
