Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2248, here are decompositions:

  • 5 + 2243 = 2248
  • 11 + 2237 = 2248
  • 41 + 2207 = 2248
  • 107 + 2141 = 2248
  • 137 + 2111 = 2248
  • 149 + 2099 = 2248
  • 167 + 2081 = 2248
  • 179 + 2069 = 2248

Showing the first eight; more decompositions exist.
