Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16158, here are decompositions:
- 17 + 16141 = 16158
- 19 + 16139 = 16158
- 31 + 16127 = 16158
- 47 + 16111 = 16158
- 61 + 16097 = 16158
- 67 + 16091 = 16158
- 71 + 16087 = 16158
- 89 + 16069 = 16158
Showing the first eight; more decompositions exist.
