Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488676, here are decompositions:

  • 29 + 31488647 = 31488676
  • 113 + 31488563 = 31488676
  • 179 + 31488497 = 31488676
  • 269 + 31488407 = 31488676
  • 347 + 31488329 = 31488676
  • 353 + 31488323 = 31488676
  • 383 + 31488293 = 31488676
  • 419 + 31488257 = 31488676

Showing the first eight; more decompositions exist.
