Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55122, here are decompositions:

  • 5 + 55117 = 55122
  • 13 + 55109 = 55122
  • 19 + 55103 = 55122
  • 43 + 55079 = 55122
  • 61 + 55061 = 55122
  • 71 + 55051 = 55122
  • 73 + 55049 = 55122
  • 101 + 55021 = 55122

Showing the first eight; more decompositions exist.
