Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664392, here are decompositions:

  • 3 + 8664389 = 8664392
  • 199 + 8664193 = 8664392
  • 211 + 8664181 = 8664392
  • 283 + 8664109 = 8664392
  • 349 + 8664043 = 8664392
  • 433 + 8663959 = 8664392
  • 523 + 8663869 = 8664392
  • 571 + 8663821 = 8664392

Showing the first eight; more decompositions exist.
