Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81482, here are decompositions:

  • 19 + 81463 = 81482
  • 43 + 81439 = 81482
  • 61 + 81421 = 81482
  • 73 + 81409 = 81482
  • 109 + 81373 = 81482
  • 139 + 81343 = 81482
  • 151 + 81331 = 81482
  • 199 + 81283 = 81482

Showing the first eight; more decompositions exist.
