Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429496, here are decompositions:

  • 29 + 2147429467 = 2147429496
  • 83 + 2147429413 = 2147429496
  • 263 + 2147429233 = 2147429496
  • 283 + 2147429213 = 2147429496
  • 313 + 2147429183 = 2147429496
  • 349 + 2147429147 = 2147429496
  • 439 + 2147429057 = 2147429496
  • 449 + 2147429047 = 2147429496

Showing the first eight; more decompositions exist.
