Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81132, here are decompositions:

  • 13 + 81119 = 81132
  • 31 + 81101 = 81132
  • 61 + 81071 = 81132
  • 83 + 81049 = 81132
  • 89 + 81043 = 81132
  • 101 + 81031 = 81132
  • 109 + 81023 = 81132
  • 113 + 81019 = 81132

Showing the first eight; more decompositions exist.
