Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51536, here are decompositions:

  • 19 + 51517 = 51536
  • 97 + 51439 = 51536
  • 109 + 51427 = 51536
  • 193 + 51343 = 51536
  • 229 + 51307 = 51536
  • 307 + 51229 = 51536
  • 337 + 51199 = 51536
  • 367 + 51169 = 51536

Showing the first eight; more decompositions exist.
