Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495180, here are decompositions:

  • 19 + 495161 = 495180
  • 29 + 495151 = 495180
  • 31 + 495149 = 495180
  • 41 + 495139 = 495180
  • 47 + 495133 = 495180
  • 61 + 495119 = 495180
  • 67 + 495113 = 495180
  • 71 + 495109 = 495180

Showing the first eight; more decompositions exist.
