Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30882, here are decompositions:

  • 11 + 30871 = 30882
  • 13 + 30869 = 30882
  • 23 + 30859 = 30882
  • 29 + 30853 = 30882
  • 31 + 30851 = 30882
  • 41 + 30841 = 30882
  • 43 + 30839 = 30882
  • 53 + 30829 = 30882

Showing the first eight; more decompositions exist.
