Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85712, here are decompositions:

  • 43 + 85669 = 85712
  • 73 + 85639 = 85712
  • 163 + 85549 = 85712
  • 181 + 85531 = 85712
  • 199 + 85513 = 85712
  • 283 + 85429 = 85712
  • 331 + 85381 = 85712
  • 349 + 85363 = 85712

Showing the first eight; more decompositions exist.
