Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637784, here are decompositions:

  • 5 + 8637779 = 8637784
  • 83 + 8637701 = 8637784
  • 167 + 8637617 = 8637784
  • 173 + 8637611 = 8637784
  • 257 + 8637527 = 8637784
  • 263 + 8637521 = 8637784
  • 293 + 8637491 = 8637784
  • 317 + 8637467 = 8637784

Showing the first eight; more decompositions exist.
