Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51350, here are decompositions:

  • 3 + 51347 = 51350
  • 7 + 51343 = 51350
  • 43 + 51307 = 51350
  • 67 + 51283 = 51350
  • 109 + 51241 = 51350
  • 151 + 51199 = 51350
  • 157 + 51193 = 51350
  • 181 + 51169 = 51350

Showing the first eight; more decompositions exist.
