Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81084, here are decompositions:

  • 7 + 81077 = 81084
  • 13 + 81071 = 81084
  • 37 + 81047 = 81084
  • 41 + 81043 = 81084
  • 43 + 81041 = 81084
  • 53 + 81031 = 81084
  • 61 + 81023 = 81084
  • 67 + 81017 = 81084

Showing the first eight; more decompositions exist.
