Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17178, here are decompositions:
- 11 + 17167 = 17178
- 19 + 17159 = 17178
- 41 + 17137 = 17178
- 61 + 17117 = 17178
- 71 + 17107 = 17178
- 79 + 17099 = 17178
- 101 + 17077 = 17178
- 131 + 17047 = 17178
Showing the first eight; more decompositions exist.
