Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462210, here are decompositions:

  • 83 + 31462127 = 31462210
  • 107 + 31462103 = 31462210
  • 233 + 31461977 = 31462210
  • 317 + 31461893 = 31462210
  • 359 + 31461851 = 31462210
  • 419 + 31461791 = 31462210
  • 431 + 31461779 = 31462210
  • 449 + 31461761 = 31462210

Showing the first eight; more decompositions exist.
