Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122922, here are decompositions:
- 31 + 122891 = 122922
- 53 + 122869 = 122922
- 61 + 122861 = 122922
- 73 + 122849 = 122922
- 83 + 122839 = 122922
- 89 + 122833 = 122922
- 103 + 122819 = 122922
- 179 + 122743 = 122922
Showing the first eight; more decompositions exist.
