Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483920, here are decompositions:

  • 53 + 2147483867 = 2147483920
  • 107 + 2147483813 = 2147483920
  • 137 + 2147483783 = 2147483920
  • 227 + 2147483693 = 2147483920
  • 431 + 2147483489 = 2147483920
  • 443 + 2147483477 = 2147483920
  • 521 + 2147483399 = 2147483920
  • 683 + 2147483237 = 2147483920

Showing the first eight; more decompositions exist.
