Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468308, here are decompositions:

  • 17 + 2147468291 = 2147468308
  • 59 + 2147468249 = 2147468308
  • 239 + 2147468069 = 2147468308
  • 389 + 2147467919 = 2147468308
  • 641 + 2147467667 = 2147468308
  • 677 + 2147467631 = 2147468308
  • 929 + 2147467379 = 2147468308
  • 941 + 2147467367 = 2147468308

Showing the first eight; more decompositions exist.
