Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005942, here are decompositions:

  • 5 + 1005937 = 1005942
  • 11 + 1005931 = 1005942
  • 29 + 1005913 = 1005942
  • 31 + 1005911 = 1005942
  • 59 + 1005883 = 1005942
  • 109 + 1005833 = 1005942
  • 181 + 1005761 = 1005942
  • 191 + 1005751 = 1005942

Showing the first eight; more decompositions exist.
