Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483540, here are decompositions:

  • 43 + 2147483497 = 2147483540
  • 271 + 2147483269 = 2147483540
  • 463 + 2147483077 = 2147483540
  • 487 + 2147483053 = 2147483540
  • 619 + 2147482921 = 2147483540
  • 673 + 2147482867 = 2147483540
  • 739 + 2147482801 = 2147483540
  • 859 + 2147482681 = 2147483540

Showing the first eight; more decompositions exist.
