Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453474, here are decompositions:

  • 11 + 31453463 = 31453474
  • 47 + 31453427 = 31453474
  • 53 + 31453421 = 31453474
  • 83 + 31453391 = 31453474
  • 113 + 31453361 = 31453474
  • 191 + 31453283 = 31453474
  • 233 + 31453241 = 31453474
  • 281 + 31453193 = 31453474

Showing the first eight; more decompositions exist.
