Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122958, here are decompositions:
- 5 + 122953 = 122958
- 19 + 122939 = 122958
- 29 + 122929 = 122958
- 37 + 122921 = 122958
- 67 + 122891 = 122958
- 71 + 122887 = 122958
- 89 + 122869 = 122958
- 97 + 122861 = 122958
Showing the first eight; more decompositions exist.
