Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16172, here are decompositions:
- 31 + 16141 = 16172
- 61 + 16111 = 16172
- 103 + 16069 = 16172
- 109 + 16063 = 16172
- 139 + 16033 = 16172
- 181 + 15991 = 16172
- 199 + 15973 = 16172
- 271 + 15901 = 16172
Showing the first eight; more decompositions exist.
