Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987206, here are decompositions:

  • 7 + 987199 = 987206
  • 13 + 987193 = 987206
  • 79 + 987127 = 987206
  • 109 + 987097 = 987206
  • 127 + 987079 = 987206
  • 139 + 987067 = 987206
  • 163 + 987043 = 987206
  • 193 + 987013 = 987206

Showing the first eight; more decompositions exist.
