Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505938, here are decompositions:

  • 11 + 505927 = 505938
  • 19 + 505919 = 505938
  • 31 + 505907 = 505938
  • 61 + 505877 = 505938
  • 67 + 505871 = 505938
  • 71 + 505867 = 505938
  • 127 + 505811 = 505938
  • 157 + 505781 = 505938

Showing the first eight; more decompositions exist.
