Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678644, here are decompositions:

  • 5 + 8678639 = 8678644
  • 41 + 8678603 = 8678644
  • 137 + 8678507 = 8678644
  • 197 + 8678447 = 8678644
  • 251 + 8678393 = 8678644
  • 281 + 8678363 = 8678644
  • 311 + 8678333 = 8678644
  • 431 + 8678213 = 8678644

Showing the first eight; more decompositions exist.
