Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122238, here are decompositions:
- 7 + 122231 = 122238
- 19 + 122219 = 122238
- 29 + 122209 = 122238
- 31 + 122207 = 122238
- 37 + 122201 = 122238
- 71 + 122167 = 122238
- 89 + 122149 = 122238
- 107 + 122131 = 122238
Showing the first eight; more decompositions exist.
