Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448252, here are decompositions:

  • 19 + 31448233 = 31448252
  • 61 + 31448191 = 31448252
  • 103 + 31448149 = 31448252
  • 181 + 31448071 = 31448252
  • 229 + 31448023 = 31448252
  • 349 + 31447903 = 31448252
  • 439 + 31447813 = 31448252
  • 571 + 31447681 = 31448252

Showing the first eight; more decompositions exist.
