Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519234, here are decompositions:

  • 23 + 31519211 = 31519234
  • 41 + 31519193 = 31519234
  • 53 + 31519181 = 31519234
  • 83 + 31519151 = 31519234
  • 113 + 31519121 = 31519234
  • 167 + 31519067 = 31519234
  • 281 + 31518953 = 31519234
  • 311 + 31518923 = 31519234

Showing the first eight; more decompositions exist.
