Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31882, here are decompositions:

  • 23 + 31859 = 31882
  • 83 + 31799 = 31882
  • 89 + 31793 = 31882
  • 113 + 31769 = 31882
  • 131 + 31751 = 31882
  • 233 + 31649 = 31882
  • 239 + 31643 = 31882
  • 281 + 31601 = 31882

Showing the first eight; more decompositions exist.
