Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481492, here are decompositions:

  • 5 + 2147481487 = 2147481492
  • 139 + 2147481353 = 2147481492
  • 181 + 2147481311 = 2147481492
  • 223 + 2147481269 = 2147481492
  • 229 + 2147481263 = 2147481492
  • 283 + 2147481209 = 2147481492
  • 293 + 2147481199 = 2147481492
  • 313 + 2147481179 = 2147481492

Showing the first eight; more decompositions exist.
