Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452946, here are decompositions:

  • 3 + 31452943 = 31452946
  • 197 + 31452749 = 31452946
  • 227 + 31452719 = 31452946
  • 263 + 31452683 = 31452946
  • 269 + 31452677 = 31452946
  • 347 + 31452599 = 31452946
  • 359 + 31452587 = 31452946
  • 419 + 31452527 = 31452946

Showing the first eight; more decompositions exist.
