Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486456, here are decompositions:

  • 3 + 31486453 = 31486456
  • 5 + 31486451 = 31486456
  • 107 + 31486349 = 31486456
  • 149 + 31486307 = 31486456
  • 167 + 31486289 = 31486456
  • 173 + 31486283 = 31486456
  • 227 + 31486229 = 31486456
  • 293 + 31486163 = 31486456

Showing the first eight; more decompositions exist.
