Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618784, here are decompositions:

  • 37 + 8618747 = 8618784
  • 47 + 8618737 = 8618784
  • 101 + 8618683 = 8618784
  • 103 + 8618681 = 8618784
  • 191 + 8618593 = 8618784
  • 193 + 8618591 = 8618784
  • 227 + 8618557 = 8618784
  • 283 + 8618501 = 8618784

Showing the first eight; more decompositions exist.
