Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453434, here are decompositions:

  • 7 + 31453427 = 31453434
  • 13 + 31453421 = 31453434
  • 41 + 31453393 = 31453434
  • 43 + 31453391 = 31453434
  • 73 + 31453361 = 31453434
  • 101 + 31453333 = 31453434
  • 113 + 31453321 = 31453434
  • 151 + 31453283 = 31453434

Showing the first eight; more decompositions exist.
