Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147522428, here are decompositions:

  • 59 + 2147522369 = 2147522428
  • 101 + 2147522327 = 2147522428
  • 239 + 2147522189 = 2147522428
  • 269 + 2147522159 = 2147522428
  • 347 + 2147522081 = 2147522428
  • 419 + 2147522009 = 2147522428
  • 587 + 2147521841 = 2147522428
  • 599 + 2147521829 = 2147522428

Showing the first eight; more decompositions exist.
