Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29158, here are decompositions:
- 5 + 29153 = 29158
- 11 + 29147 = 29158
- 29 + 29129 = 29158
- 131 + 29027 = 29158
- 137 + 29021 = 29158
- 149 + 29009 = 29158
- 179 + 28979 = 29158
- 197 + 28961 = 29158
Showing the first eight; more decompositions exist.
