Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81492, here are decompositions:

  • 29 + 81463 = 81492
  • 53 + 81439 = 81492
  • 71 + 81421 = 81492
  • 83 + 81409 = 81492
  • 139 + 81353 = 81492
  • 149 + 81343 = 81492
  • 193 + 81299 = 81492
  • 199 + 81293 = 81492

Showing the first eight; more decompositions exist.
