Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477232, here are decompositions:

  • 19 + 31477213 = 31477232
  • 181 + 31477051 = 31477232
  • 211 + 31477021 = 31477232
  • 379 + 31476853 = 31477232
  • 433 + 31476799 = 31477232
  • 499 + 31476733 = 31477232
  • 541 + 31476691 = 31477232
  • 601 + 31476631 = 31477232

Showing the first eight; more decompositions exist.
