Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453800, here are decompositions:

  • 17 + 31453783 = 31453800
  • 67 + 31453733 = 31453800
  • 73 + 31453727 = 31453800
  • 89 + 31453711 = 31453800
  • 101 + 31453699 = 31453800
  • 149 + 31453651 = 31453800
  • 223 + 31453577 = 31453800
  • 229 + 31453571 = 31453800

Showing the first eight; more decompositions exist.
