Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16086, here are decompositions:
- 13 + 16073 = 16086
- 17 + 16069 = 16086
- 19 + 16067 = 16086
- 23 + 16063 = 16086
- 29 + 16057 = 16086
- 53 + 16033 = 16086
- 79 + 16007 = 16086
- 113 + 15973 = 16086
Showing the first eight; more decompositions exist.
