Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460864, here are decompositions:

  • 13 + 31460851 = 31460864
  • 31 + 31460833 = 31460864
  • 73 + 31460791 = 31460864
  • 163 + 31460701 = 31460864
  • 283 + 31460581 = 31460864
  • 313 + 31460551 = 31460864
  • 367 + 31460497 = 31460864
  • 373 + 31460491 = 31460864

Showing the first eight; more decompositions exist.
