Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51164, here are decompositions:

  • 7 + 51157 = 51164
  • 13 + 51151 = 51164
  • 31 + 51133 = 51164
  • 103 + 51061 = 51164
  • 163 + 51001 = 51164
  • 193 + 50971 = 51164
  • 241 + 50923 = 51164
  • 271 + 50893 = 51164

Showing the first eight; more decompositions exist.
