Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2256, here are decompositions:

  • 5 + 2251 = 2256
  • 13 + 2243 = 2256
  • 17 + 2239 = 2256
  • 19 + 2237 = 2256
  • 43 + 2213 = 2256
  • 53 + 2203 = 2256
  • 103 + 2153 = 2256
  • 113 + 2143 = 2256

Showing the first eight; more decompositions exist.
