Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527682, here are decompositions:

  • 5 + 31527677 = 31527682
  • 23 + 31527659 = 31527682
  • 113 + 31527569 = 31527682
  • 149 + 31527533 = 31527682
  • 191 + 31527491 = 31527682
  • 269 + 31527413 = 31527682
  • 293 + 31527389 = 31527682
  • 359 + 31527323 = 31527682

Showing the first eight; more decompositions exist.
