Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542434, here are decompositions:

  • 37 + 31542397 = 31542434
  • 43 + 31542391 = 31542434
  • 61 + 31542373 = 31542434
  • 271 + 31542163 = 31542434
  • 331 + 31542103 = 31542434
  • 367 + 31542067 = 31542434
  • 397 + 31542037 = 31542434
  • 421 + 31542013 = 31542434

Showing the first eight; more decompositions exist.
