Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147588518, here are decompositions:

  • 17 + 2147588501 = 2147588518
  • 29 + 2147588489 = 2147588518
  • 137 + 2147588381 = 2147588518
  • 197 + 2147588321 = 2147588518
  • 239 + 2147588279 = 2147588518
  • 281 + 2147588237 = 2147588518
  • 401 + 2147588117 = 2147588518
  • 419 + 2147588099 = 2147588518

Showing the first eight; more decompositions exist.
