Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454212, here are decompositions:

  • 11 + 31454201 = 31454212
  • 89 + 31454123 = 31454212
  • 131 + 31454081 = 31454212
  • 269 + 31453943 = 31454212
  • 281 + 31453931 = 31454212
  • 389 + 31453823 = 31454212
  • 479 + 31453733 = 31454212
  • 641 + 31453571 = 31454212

Showing the first eight; more decompositions exist.
