Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448300, here are decompositions:

  • 3 + 31448297 = 31448300
  • 7 + 31448293 = 31448300
  • 19 + 31448281 = 31448300
  • 67 + 31448233 = 31448300
  • 109 + 31448191 = 31448300
  • 139 + 31448161 = 31448300
  • 151 + 31448149 = 31448300
  • 229 + 31448071 = 31448300

Showing the first eight; more decompositions exist.
