Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495880, here are decompositions:

  • 3 + 495877 = 495880
  • 29 + 495851 = 495880
  • 53 + 495827 = 495880
  • 59 + 495821 = 495880
  • 83 + 495797 = 495880
  • 89 + 495791 = 495880
  • 107 + 495773 = 495880
  • 131 + 495749 = 495880

Showing the first eight; more decompositions exist.
