Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497166, here are decompositions:

  • 127 + 2147497039 = 2147497166
  • 229 + 2147496937 = 2147497166
  • 307 + 2147496859 = 2147497166
  • 313 + 2147496853 = 2147497166
  • 337 + 2147496829 = 2147497166
  • 349 + 2147496817 = 2147497166
  • 433 + 2147496733 = 2147497166
  • 823 + 2147496343 = 2147497166

Showing the first eight; more decompositions exist.
