Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553122, here are decompositions:

  • 53 + 31553069 = 31553122
  • 59 + 31553063 = 31553122
  • 101 + 31553021 = 31553122
  • 179 + 31552943 = 31553122
  • 239 + 31552883 = 31553122
  • 269 + 31552853 = 31553122
  • 389 + 31552733 = 31553122
  • 401 + 31552721 = 31553122

Showing the first eight; more decompositions exist.
