Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483880, here are decompositions:

  • 11 + 2147483869 = 2147483880
  • 13 + 2147483867 = 2147483880
  • 23 + 2147483857 = 2147483880
  • 67 + 2147483813 = 2147483880
  • 97 + 2147483783 = 2147483880
  • 103 + 2147483777 = 2147483880
  • 137 + 2147483743 = 2147483880
  • 167 + 2147483713 = 2147483880

Showing the first eight; more decompositions exist.
