Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 260, here are decompositions:

  • 3 + 257 = 260
  • 19 + 241 = 260
  • 31 + 229 = 260
  • 37 + 223 = 260
  • 61 + 199 = 260
  • 67 + 193 = 260
  • 79 + 181 = 260
  • 97 + 163 = 260

Showing the first eight; more decompositions exist.
