Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613332, here are decompositions:

  • 41 + 31613291 = 31613332
  • 83 + 31613249 = 31613332
  • 89 + 31613243 = 31613332
  • 419 + 31612913 = 31613332
  • 479 + 31612853 = 31613332
  • 593 + 31612739 = 31613332
  • 599 + 31612733 = 31613332
  • 743 + 31612589 = 31613332

Showing the first eight; more decompositions exist.
