Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105122, here are decompositions:
- 103 + 105019 = 105122
- 151 + 104971 = 105122
- 163 + 104959 = 105122
- 211 + 104911 = 105122
- 271 + 104851 = 105122
- 349 + 104773 = 105122
- 379 + 104743 = 105122
- 421 + 104701 = 105122
Showing the first eight; more decompositions exist.
