Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518496, here are decompositions:

  • 5 + 31518491 = 31518496
  • 29 + 31518467 = 31518496
  • 167 + 31518329 = 31518496
  • 257 + 31518239 = 31518496
  • 587 + 31517909 = 31518496
  • 617 + 31517879 = 31518496
  • 773 + 31517723 = 31518496
  • 797 + 31517699 = 31518496

Showing the first eight; more decompositions exist.
