Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712644, here are decompositions:

  • 43 + 8712601 = 8712644
  • 67 + 8712577 = 8712644
  • 97 + 8712547 = 8712644
  • 223 + 8712421 = 8712644
  • 271 + 8712373 = 8712644
  • 277 + 8712367 = 8712644
  • 307 + 8712337 = 8712644
  • 337 + 8712307 = 8712644

Showing the first eight; more decompositions exist.
