Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472722, here are decompositions:

  • 223 + 2147472499 = 2147472722
  • 349 + 2147472373 = 2147472722
  • 379 + 2147472343 = 2147472722
  • 433 + 2147472289 = 2147472722
  • 463 + 2147472259 = 2147472722
  • 523 + 2147472199 = 2147472722
  • 613 + 2147472109 = 2147472722
  • 631 + 2147472091 = 2147472722

Showing the first eight; more decompositions exist.
