Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483428, here are decompositions:

  • 5 + 2147483423 = 2147483428
  • 29 + 2147483399 = 2147483428
  • 179 + 2147483249 = 2147483428
  • 191 + 2147483237 = 2147483428
  • 257 + 2147483171 = 2147483428
  • 359 + 2147483069 = 2147483428
  • 479 + 2147482949 = 2147483428
  • 491 + 2147482937 = 2147483428

Showing the first eight; more decompositions exist.
