Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452444, here are decompositions:

  • 43 + 31452401 = 31452444
  • 103 + 31452341 = 31452444
  • 211 + 31452233 = 31452444
  • 241 + 31452203 = 31452444
  • 263 + 31452181 = 31452444
  • 271 + 31452173 = 31452444
  • 307 + 31452137 = 31452444
  • 313 + 31452131 = 31452444

Showing the first eight; more decompositions exist.
