Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147578204, here are decompositions:

  • 41 + 2147578163 = 2147578204
  • 137 + 2147578067 = 2147578204
  • 173 + 2147578031 = 2147578204
  • 197 + 2147578007 = 2147578204
  • 311 + 2147577893 = 2147578204
  • 347 + 2147577857 = 2147578204
  • 383 + 2147577821 = 2147578204
  • 557 + 2147577647 = 2147578204

Showing the first eight; more decompositions exist.
