Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115122, here are decompositions:
- 5 + 115117 = 115122
- 23 + 115099 = 115122
- 43 + 115079 = 115122
- 61 + 115061 = 115122
- 101 + 115021 = 115122
- 103 + 115019 = 115122
- 109 + 115013 = 115122
- 149 + 114973 = 115122
Showing the first eight; more decompositions exist.
