Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11278, here are decompositions:

  • 5 + 11273 = 11278
  • 17 + 11261 = 11278
  • 101 + 11177 = 11278
  • 107 + 11171 = 11278
  • 191 + 11087 = 11278
  • 251 + 11027 = 11278
  • 389 + 10889 = 11278
  • 419 + 10859 = 11278

Showing the first eight; more decompositions exist.
