Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501918, here are decompositions:

  • 31 + 2147501887 = 2147501918
  • 97 + 2147501821 = 2147501918
  • 241 + 2147501677 = 2147501918
  • 307 + 2147501611 = 2147501918
  • 439 + 2147501479 = 2147501918
  • 487 + 2147501431 = 2147501918
  • 787 + 2147501131 = 2147501918
  • 829 + 2147501089 = 2147501918

Showing the first eight; more decompositions exist.
