Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979440, here are decompositions:

  • 17 + 979423 = 979440
  • 37 + 979403 = 979440
  • 61 + 979379 = 979440
  • 67 + 979373 = 979440
  • 71 + 979369 = 979440
  • 79 + 979361 = 979440
  • 97 + 979343 = 979440
  • 103 + 979337 = 979440

Showing the first eight; more decompositions exist.
