Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453746, here are decompositions:

  • 13 + 31453733 = 31453746
  • 19 + 31453727 = 31453746
  • 47 + 31453699 = 31453746
  • 67 + 31453679 = 31453746
  • 223 + 31453523 = 31453746
  • 239 + 31453507 = 31453746
  • 263 + 31453483 = 31453746
  • 283 + 31453463 = 31453746

Showing the first eight; more decompositions exist.
