Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462240, here are decompositions:

  • 23 + 31462217 = 31462240
  • 107 + 31462133 = 31462240
  • 113 + 31462127 = 31462240
  • 137 + 31462103 = 31462240
  • 233 + 31462007 = 31462240
  • 263 + 31461977 = 31462240
  • 317 + 31461923 = 31462240
  • 347 + 31461893 = 31462240

Showing the first eight; more decompositions exist.
