Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476392, here are decompositions:

  • 19 + 31476373 = 31476392
  • 43 + 31476349 = 31476392
  • 109 + 31476283 = 31476392
  • 223 + 31476169 = 31476392
  • 379 + 31476013 = 31476392
  • 439 + 31475953 = 31476392
  • 463 + 31475929 = 31476392
  • 613 + 31475779 = 31476392

Showing the first eight; more decompositions exist.
