Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466874, here are decompositions:

  • 5 + 2147466869 = 2147466874
  • 41 + 2147466833 = 2147466874
  • 173 + 2147466701 = 2147466874
  • 191 + 2147466683 = 2147466874
  • 233 + 2147466641 = 2147466874
  • 353 + 2147466521 = 2147466874
  • 491 + 2147466383 = 2147466874
  • 617 + 2147466257 = 2147466874

Showing the first eight; more decompositions exist.
