Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497692, here are decompositions:

  • 29 + 2147497663 = 2147497692
  • 31 + 2147497661 = 2147497692
  • 199 + 2147497493 = 2147497692
  • 211 + 2147497481 = 2147497692
  • 233 + 2147497459 = 2147497692
  • 281 + 2147497411 = 2147497692
  • 331 + 2147497361 = 2147497692
  • 449 + 2147497243 = 2147497692

Showing the first eight; more decompositions exist.
