Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147560166, here are decompositions:

  • 67 + 2147560099 = 2147560166
  • 127 + 2147560039 = 2147560166
  • 313 + 2147559853 = 2147560166
  • 613 + 2147559553 = 2147560166
  • 709 + 2147559457 = 2147560166
  • 823 + 2147559343 = 2147560166
  • 859 + 2147559307 = 2147560166
  • 919 + 2147559247 = 2147560166

Showing the first eight; more decompositions exist.
