Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15122, here are decompositions:
- 31 + 15091 = 15122
- 61 + 15061 = 15122
- 109 + 15013 = 15122
- 139 + 14983 = 15122
- 193 + 14929 = 15122
- 199 + 14923 = 15122
- 271 + 14851 = 15122
- 409 + 14713 = 15122
Showing the first eight; more decompositions exist.
