Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2080, here are decompositions:

  • 11 + 2069 = 2080
  • 17 + 2063 = 2080
  • 41 + 2039 = 2080
  • 53 + 2027 = 2080
  • 83 + 1997 = 2080
  • 101 + 1979 = 2080
  • 107 + 1973 = 2080
  • 131 + 1949 = 2080

Showing the first eight; more decompositions exist.
