Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449244, here are decompositions:

  • 3 + 31449241 = 31449244
  • 11 + 31449233 = 31449244
  • 53 + 31449191 = 31449244
  • 173 + 31449071 = 31449244
  • 191 + 31449053 = 31449244
  • 227 + 31449017 = 31449244
  • 257 + 31448987 = 31449244
  • 347 + 31448897 = 31449244

Showing the first eight; more decompositions exist.
