Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71880, here are decompositions:

  • 13 + 71867 = 71880
  • 19 + 71861 = 71880
  • 31 + 71849 = 71880
  • 37 + 71843 = 71880
  • 43 + 71837 = 71880
  • 59 + 71821 = 71880
  • 71 + 71809 = 71880
  • 73 + 71807 = 71880

Showing the first eight; more decompositions exist.
