Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452392, here are decompositions:

  • 109 + 31452283 = 31452392
  • 151 + 31452241 = 31452392
  • 193 + 31452199 = 31452392
  • 211 + 31452181 = 31452392
  • 271 + 31452121 = 31452392
  • 313 + 31452079 = 31452392
  • 331 + 31452061 = 31452392
  • 373 + 31452019 = 31452392

Showing the first eight; more decompositions exist.
