Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32880, here are decompositions:

  • 11 + 32869 = 32880
  • 37 + 32843 = 32880
  • 41 + 32839 = 32880
  • 47 + 32833 = 32880
  • 79 + 32801 = 32880
  • 83 + 32797 = 32880
  • 97 + 32783 = 32880
  • 101 + 32779 = 32880

Showing the first eight; more decompositions exist.
