Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483956, here are decompositions:

  • 5 + 2147483951 = 2147483956
  • 89 + 2147483867 = 2147483956
  • 173 + 2147483783 = 2147483956
  • 179 + 2147483777 = 2147483956
  • 263 + 2147483693 = 2147483956
  • 467 + 2147483489 = 2147483956
  • 479 + 2147483477 = 2147483956
  • 557 + 2147483399 = 2147483956

Showing the first eight; more decompositions exist.
