Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147541166, here are decompositions:

  • 233 + 2147540933 = 2147541166
  • 383 + 2147540783 = 2147541166
  • 467 + 2147540699 = 2147541166
  • 569 + 2147540597 = 2147541166
  • 647 + 2147540519 = 2147541166
  • 887 + 2147540279 = 2147541166
  • 929 + 2147540237 = 2147541166
  • 1103 + 2147540063 = 2147541166

Showing the first eight; more decompositions exist.
