Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453256, here are decompositions:

  • 7 + 31453249 = 31453256
  • 97 + 31453159 = 31453256
  • 283 + 31452973 = 31453256
  • 313 + 31452943 = 31453256
  • 397 + 31452859 = 31453256
  • 463 + 31452793 = 31453256
  • 487 + 31452769 = 31453256
  • 607 + 31452649 = 31453256

Showing the first eight; more decompositions exist.
