Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474832, here are decompositions:

  • 3 + 31474829 = 31474832
  • 31 + 31474801 = 31474832
  • 139 + 31474693 = 31474832
  • 163 + 31474669 = 31474832
  • 283 + 31474549 = 31474832
  • 313 + 31474519 = 31474832
  • 331 + 31474501 = 31474832
  • 409 + 31474423 = 31474832

Showing the first eight; more decompositions exist.
