Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495986, here are decompositions:

  • 3 + 495983 = 495986
  • 13 + 495973 = 495986
  • 19 + 495967 = 495986
  • 109 + 495877 = 495986
  • 157 + 495829 = 495986
  • 199 + 495787 = 495986
  • 229 + 495757 = 495986
  • 307 + 495679 = 495986

Showing the first eight; more decompositions exist.
