Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508524, here are decompositions:

  • 17 + 31508507 = 31508524
  • 71 + 31508453 = 31508524
  • 107 + 31508417 = 31508524
  • 293 + 31508231 = 31508524
  • 347 + 31508177 = 31508524
  • 353 + 31508171 = 31508524
  • 431 + 31508093 = 31508524
  • 521 + 31508003 = 31508524

Showing the first eight; more decompositions exist.
