Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469876, here are decompositions:

  • 47 + 2147469829 = 2147469876
  • 53 + 2147469823 = 2147469876
  • 59 + 2147469817 = 2147469876
  • 173 + 2147469703 = 2147469876
  • 197 + 2147469679 = 2147469876
  • 239 + 2147469637 = 2147469876
  • 257 + 2147469619 = 2147469876
  • 283 + 2147469593 = 2147469876

Showing the first eight; more decompositions exist.
