Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16416, here are decompositions:
- 5 + 16411 = 16416
- 47 + 16369 = 16416
- 53 + 16363 = 16416
- 67 + 16349 = 16416
- 83 + 16333 = 16416
- 97 + 16319 = 16416
- 149 + 16267 = 16416
- 163 + 16253 = 16416
Showing the first eight; more decompositions exist.
