Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147519212, here are decompositions:

  • 89 + 2147519123 = 2147519212
  • 131 + 2147519081 = 2147519212
  • 263 + 2147518949 = 2147519212
  • 353 + 2147518859 = 2147519212
  • 389 + 2147518823 = 2147519212
  • 491 + 2147518721 = 2147519212
  • 593 + 2147518619 = 2147519212
  • 659 + 2147518553 = 2147519212

Showing the first eight; more decompositions exist.
