Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57920, here are decompositions:

  • 3 + 57917 = 57920
  • 19 + 57901 = 57920
  • 61 + 57859 = 57920
  • 67 + 57853 = 57920
  • 73 + 57847 = 57920
  • 127 + 57793 = 57920
  • 139 + 57781 = 57920
  • 193 + 57727 = 57920

Showing the first eight; more decompositions exist.
