Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472704, here are decompositions:

  • 7 + 2147472697 = 2147472704
  • 103 + 2147472601 = 2147472704
  • 283 + 2147472421 = 2147472704
  • 331 + 2147472373 = 2147472704
  • 571 + 2147472133 = 2147472704
  • 613 + 2147472091 = 2147472704
  • 661 + 2147472043 = 2147472704
  • 823 + 2147471881 = 2147472704

Showing the first eight; more decompositions exist.
