Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122920, here are decompositions:
- 29 + 122891 = 122920
- 53 + 122867 = 122920
- 59 + 122861 = 122920
- 71 + 122849 = 122920
- 101 + 122819 = 122920
- 131 + 122789 = 122920
- 167 + 122753 = 122920
- 179 + 122741 = 122920
Showing the first eight; more decompositions exist.
