Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472830, here are decompositions:

  • 43 + 2147472787 = 2147472830
  • 73 + 2147472757 = 2147472830
  • 79 + 2147472751 = 2147472830
  • 229 + 2147472601 = 2147472830
  • 331 + 2147472499 = 2147472830
  • 409 + 2147472421 = 2147472830
  • 457 + 2147472373 = 2147472830
  • 487 + 2147472343 = 2147472830

Showing the first eight; more decompositions exist.
