Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605848, here are decompositions:

  • 37 + 31605811 = 31605848
  • 67 + 31605781 = 31605848
  • 151 + 31605697 = 31605848
  • 229 + 31605619 = 31605848
  • 271 + 31605577 = 31605848
  • 277 + 31605571 = 31605848
  • 331 + 31605517 = 31605848
  • 409 + 31605439 = 31605848

Showing the first eight; more decompositions exist.
