Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51266, here are decompositions:

  • 3 + 51263 = 51266
  • 37 + 51229 = 51266
  • 67 + 51199 = 51266
  • 73 + 51193 = 51266
  • 97 + 51169 = 51266
  • 109 + 51157 = 51266
  • 157 + 51109 = 51266
  • 223 + 51043 = 51266

Showing the first eight; more decompositions exist.
