Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611818, here are decompositions:

  • 29 + 8611789 = 8611818
  • 97 + 8611721 = 8611818
  • 109 + 8611709 = 8611818
  • 139 + 8611679 = 8611818
  • 151 + 8611667 = 8611818
  • 199 + 8611619 = 8611818
  • 269 + 8611549 = 8611818
  • 317 + 8611501 = 8611818

Showing the first eight; more decompositions exist.
