Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147435698, here are decompositions:

  • 197 + 2147435501 = 2147435698
  • 281 + 2147435417 = 2147435698
  • 449 + 2147435249 = 2147435698
  • 557 + 2147435141 = 2147435698
  • 641 + 2147435057 = 2147435698
  • 659 + 2147435039 = 2147435698
  • 719 + 2147434979 = 2147435698
  • 827 + 2147434871 = 2147435698

Showing the first eight; more decompositions exist.
