Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89880, here are decompositions:

  • 13 + 89867 = 89880
  • 31 + 89849 = 89880
  • 41 + 89839 = 89880
  • 47 + 89833 = 89880
  • 59 + 89821 = 89880
  • 61 + 89819 = 89880
  • 71 + 89809 = 89880
  • 83 + 89797 = 89880

Showing the first eight; more decompositions exist.
