Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486462, here are decompositions:

  • 5 + 31486457 = 31486462
  • 11 + 31486451 = 31486462
  • 71 + 31486391 = 31486462
  • 113 + 31486349 = 31486462
  • 173 + 31486289 = 31486462
  • 179 + 31486283 = 31486462
  • 191 + 31486271 = 31486462
  • 233 + 31486229 = 31486462

Showing the first eight; more decompositions exist.
