Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147518822, here are decompositions:

  • 101 + 2147518721 = 2147518822
  • 233 + 2147518589 = 2147518822
  • 269 + 2147518553 = 2147518822
  • 359 + 2147518463 = 2147518822
  • 389 + 2147518433 = 2147518822
  • 431 + 2147518391 = 2147518822
  • 479 + 2147518343 = 2147518822
  • 593 + 2147518229 = 2147518822

Showing the first eight; more decompositions exist.
