Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545588, here are decompositions:

  • 89 + 31545499 = 31545588
  • 101 + 31545487 = 31545588
  • 149 + 31545439 = 31545588
  • 181 + 31545407 = 31545588
  • 197 + 31545391 = 31545588
  • 257 + 31545331 = 31545588
  • 271 + 31545317 = 31545588
  • 367 + 31545221 = 31545588

Showing the first eight; more decompositions exist.
