Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86122, here are decompositions:
- 5 + 86117 = 86122
- 11 + 86111 = 86122
- 53 + 86069 = 86122
- 131 + 85991 = 86122
- 191 + 85931 = 86122
- 233 + 85889 = 86122
- 269 + 85853 = 86122
- 293 + 85829 = 86122
Showing the first eight; more decompositions exist.
