Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483656, here are decompositions:

  • 107 + 2147483549 = 2147483656
  • 113 + 2147483543 = 2147483656
  • 167 + 2147483489 = 2147483656
  • 179 + 2147483477 = 2147483656
  • 233 + 2147483423 = 2147483656
  • 257 + 2147483399 = 2147483656
  • 419 + 2147483237 = 2147483656
  • 587 + 2147483069 = 2147483656

Showing the first eight; more decompositions exist.
