Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4394, here are decompositions:

  • 3 + 4391 = 4394
  • 31 + 4363 = 4394
  • 37 + 4357 = 4394
  • 67 + 4327 = 4394
  • 97 + 4297 = 4394
  • 151 + 4243 = 4394
  • 163 + 4231 = 4394
  • 193 + 4201 = 4394

Showing the first eight; more decompositions exist.
