Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662656, here are decompositions:

  • 7 + 8662649 = 8662656
  • 59 + 8662597 = 8662656
  • 73 + 8662583 = 8662656
  • 103 + 8662553 = 8662656
  • 139 + 8662517 = 8662656
  • 173 + 8662483 = 8662656
  • 307 + 8662349 = 8662656
  • 313 + 8662343 = 8662656

Showing the first eight; more decompositions exist.
