Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13122, here are decompositions:
- 13 + 13109 = 13122
- 19 + 13103 = 13122
- 23 + 13099 = 13122
- 29 + 13093 = 13122
- 59 + 13063 = 13122
- 73 + 13049 = 13122
- 79 + 13043 = 13122
- 89 + 13033 = 13122
Showing the first eight; more decompositions exist.
