Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460782, here are decompositions:

  • 53 + 31460729 = 31460782
  • 173 + 31460609 = 31460782
  • 233 + 31460549 = 31460782
  • 383 + 31460399 = 31460782
  • 443 + 31460339 = 31460782
  • 461 + 31460321 = 31460782
  • 491 + 31460291 = 31460782
  • 503 + 31460279 = 31460782

Showing the first eight; more decompositions exist.
