Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469528, here are decompositions:

  • 61 + 31469467 = 31469528
  • 229 + 31469299 = 31469528
  • 241 + 31469287 = 31469528
  • 331 + 31469197 = 31469528
  • 397 + 31469131 = 31469528
  • 487 + 31469041 = 31469528
  • 751 + 31468777 = 31469528
  • 829 + 31468699 = 31469528

Showing the first eight; more decompositions exist.
