Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122278, here are decompositions:
- 5 + 122273 = 122278
- 11 + 122267 = 122278
- 47 + 122231 = 122278
- 59 + 122219 = 122278
- 71 + 122207 = 122278
- 131 + 122147 = 122278
- 179 + 122099 = 122278
- 197 + 122081 = 122278
Showing the first eight; more decompositions exist.
