Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404676, here are decompositions:

  • 37 + 2147404639 = 2147404676
  • 97 + 2147404579 = 2147404676
  • 229 + 2147404447 = 2147404676
  • 283 + 2147404393 = 2147404676
  • 349 + 2147404327 = 2147404676
  • 367 + 2147404309 = 2147404676
  • 433 + 2147404243 = 2147404676
  • 523 + 2147404153 = 2147404676

Showing the first eight; more decompositions exist.
