Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706784, here are decompositions:

  • 41 + 8706743 = 8706784
  • 113 + 8706671 = 8706784
  • 137 + 8706647 = 8706784
  • 173 + 8706611 = 8706784
  • 197 + 8706587 = 8706784
  • 227 + 8706557 = 8706784
  • 257 + 8706527 = 8706784
  • 461 + 8706323 = 8706784

Showing the first eight; more decompositions exist.
