Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627342, here are decompositions:

  • 23 + 31627319 = 31627342
  • 53 + 31627289 = 31627342
  • 191 + 31627151 = 31627342
  • 251 + 31627091 = 31627342
  • 269 + 31627073 = 31627342
  • 443 + 31626899 = 31627342
  • 449 + 31626893 = 31627342
  • 503 + 31626839 = 31627342

Showing the first eight; more decompositions exist.
