Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469906, here are decompositions:

  • 83 + 2147469823 = 2147469906
  • 89 + 2147469817 = 2147469906
  • 227 + 2147469679 = 2147469906
  • 269 + 2147469637 = 2147469906
  • 277 + 2147469629 = 2147469906
  • 313 + 2147469593 = 2147469906
  • 353 + 2147469553 = 2147469906
  • 443 + 2147469463 = 2147469906

Showing the first eight; more decompositions exist.
