Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469774, here are decompositions:

  • 71 + 2147469703 = 2147469774
  • 137 + 2147469637 = 2147469774
  • 181 + 2147469593 = 2147469774
  • 283 + 2147469491 = 2147469774
  • 311 + 2147469463 = 2147469774
  • 353 + 2147469421 = 2147469774
  • 491 + 2147469283 = 2147469774
  • 503 + 2147469271 = 2147469774

Showing the first eight; more decompositions exist.
