Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2270, here are decompositions:

  • 3 + 2267 = 2270
  • 19 + 2251 = 2270
  • 31 + 2239 = 2270
  • 67 + 2203 = 2270
  • 109 + 2161 = 2270
  • 127 + 2143 = 2270
  • 139 + 2131 = 2270
  • 157 + 2113 = 2270

Showing the first eight; more decompositions exist.
