Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464250, here are decompositions:

  • 17 + 31464233 = 31464250
  • 101 + 31464149 = 31464250
  • 107 + 31464143 = 31464250
  • 113 + 31464137 = 31464250
  • 353 + 31463897 = 31464250
  • 359 + 31463891 = 31464250
  • 401 + 31463849 = 31464250
  • 443 + 31463807 = 31464250

Showing the first eight; more decompositions exist.
