Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82540, here are decompositions:

  • 11 + 82529 = 82540
  • 41 + 82499 = 82540
  • 47 + 82493 = 82540
  • 53 + 82487 = 82540
  • 71 + 82469 = 82540
  • 83 + 82457 = 82540
  • 167 + 82373 = 82540
  • 179 + 82361 = 82540

Showing the first eight; more decompositions exist.
