Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639756, here are decompositions:

  • 3 + 8639753 = 8639756
  • 7 + 8639749 = 8639756
  • 43 + 8639713 = 8639756
  • 109 + 8639647 = 8639756
  • 157 + 8639599 = 8639756
  • 193 + 8639563 = 8639756
  • 313 + 8639443 = 8639756
  • 409 + 8639347 = 8639756

Showing the first eight; more decompositions exist.
