Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47880, here are decompositions:

  • 11 + 47869 = 47880
  • 23 + 47857 = 47880
  • 37 + 47843 = 47880
  • 43 + 47837 = 47880
  • 61 + 47819 = 47880
  • 71 + 47809 = 47880
  • 73 + 47807 = 47880
  • 83 + 47797 = 47880

Showing the first eight; more decompositions exist.
