Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467934, here are decompositions:

  • 13 + 2147467921 = 2147467934
  • 223 + 2147467711 = 2147467934
  • 307 + 2147467627 = 2147467934
  • 463 + 2147467471 = 2147467934
  • 541 + 2147467393 = 2147467934
  • 607 + 2147467327 = 2147467934
  • 613 + 2147467321 = 2147467934
  • 673 + 2147467261 = 2147467934

Showing the first eight; more decompositions exist.
