Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473972, here are decompositions:

  • 191 + 2147473781 = 2147473972
  • 239 + 2147473733 = 2147473972
  • 269 + 2147473703 = 2147473972
  • 419 + 2147473553 = 2147473972
  • 503 + 2147473469 = 2147473972
  • 563 + 2147473409 = 2147473972
  • 599 + 2147473373 = 2147473972
  • 641 + 2147473331 = 2147473972

Showing the first eight; more decompositions exist.
