Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469424, here are decompositions:

  • 3 + 2147469421 = 2147469424
  • 5 + 2147469419 = 2147469424
  • 251 + 2147469173 = 2147469424
  • 293 + 2147469131 = 2147469424
  • 311 + 2147469113 = 2147469424
  • 383 + 2147469041 = 2147469424
  • 431 + 2147468993 = 2147469424
  • 491 + 2147468933 = 2147469424

Showing the first eight; more decompositions exist.
