Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497930, here are decompositions:

  • 23 + 2147497907 = 2147497930
  • 29 + 2147497901 = 2147497930
  • 41 + 2147497889 = 2147497930
  • 173 + 2147497757 = 2147497930
  • 197 + 2147497733 = 2147497930
  • 233 + 2147497697 = 2147497930
  • 239 + 2147497691 = 2147497930
  • 269 + 2147497661 = 2147497930

Showing the first eight; more decompositions exist.
