Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461470, here are decompositions:

  • 13 + 31461457 = 31461470
  • 43 + 31461427 = 31461470
  • 67 + 31461403 = 31461470
  • 109 + 31461361 = 31461470
  • 127 + 31461343 = 31461470
  • 241 + 31461229 = 31461470
  • 277 + 31461193 = 31461470
  • 307 + 31461163 = 31461470

Showing the first eight; more decompositions exist.
