Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496400, here are decompositions:

  • 11 + 31496389 = 31496400
  • 29 + 31496371 = 31496400
  • 31 + 31496369 = 31496400
  • 71 + 31496329 = 31496400
  • 79 + 31496321 = 31496400
  • 83 + 31496317 = 31496400
  • 107 + 31496293 = 31496400
  • 137 + 31496263 = 31496400

Showing the first eight; more decompositions exist.
