Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5122, here are decompositions:
- 3 + 5119 = 5122
- 23 + 5099 = 5122
- 41 + 5081 = 5122
- 71 + 5051 = 5122
- 83 + 5039 = 5122
- 101 + 5021 = 5122
- 113 + 5009 = 5122
- 149 + 4973 = 5122
Showing the first eight; more decompositions exist.
