Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147518424, here are decompositions:

  • 43 + 2147518381 = 2147518424
  • 61 + 2147518363 = 2147518424
  • 223 + 2147518201 = 2147518424
  • 307 + 2147518117 = 2147518424
  • 463 + 2147517961 = 2147518424
  • 823 + 2147517601 = 2147518424
  • 1033 + 2147517391 = 2147518424
  • 1093 + 2147517331 = 2147518424

Showing the first eight; more decompositions exist.
