Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486, here are decompositions:

  • 5 + 31481 = 31486
  • 17 + 31469 = 31486
  • 89 + 31397 = 31486
  • 107 + 31379 = 31486
  • 149 + 31337 = 31486
  • 167 + 31319 = 31486
  • 179 + 31307 = 31486
  • 227 + 31259 = 31486

Showing the first eight; more decompositions exist.
