Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740784, here are decompositions:

  • 103 + 8740681 = 8740784
  • 127 + 8740657 = 8740784
  • 181 + 8740603 = 8740784
  • 193 + 8740591 = 8740784
  • 223 + 8740561 = 8740784
  • 331 + 8740453 = 8740784
  • 337 + 8740447 = 8740784
  • 373 + 8740411 = 8740784

Showing the first eight; more decompositions exist.
