Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429888, here are decompositions:

  • 7 + 2147429881 = 2147429888
  • 61 + 2147429827 = 2147429888
  • 199 + 2147429689 = 2147429888
  • 229 + 2147429659 = 2147429888
  • 277 + 2147429611 = 2147429888
  • 421 + 2147429467 = 2147429888
  • 577 + 2147429311 = 2147429888
  • 607 + 2147429281 = 2147429888

Showing the first eight; more decompositions exist.
