Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483470, here are decompositions:

  • 47 + 2147483423 = 2147483470
  • 71 + 2147483399 = 2147483470
  • 233 + 2147483237 = 2147483470
  • 347 + 2147483123 = 2147483470
  • 401 + 2147483069 = 2147483470
  • 521 + 2147482949 = 2147483470
  • 593 + 2147482877 = 2147483470
  • 653 + 2147482817 = 2147483470

Showing the first eight; more decompositions exist.
