Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534434, here are decompositions:

  • 5 + 31534429 = 31534434
  • 7 + 31534427 = 31534434
  • 11 + 31534423 = 31534434
  • 23 + 31534411 = 31534434
  • 101 + 31534333 = 31534434
  • 137 + 31534297 = 31534434
  • 163 + 31534271 = 31534434
  • 193 + 31534241 = 31534434

Showing the first eight; more decompositions exist.
