Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31222, here are decompositions:
- 3 + 31219 = 31222
- 29 + 31193 = 31222
- 41 + 31181 = 31222
- 71 + 31151 = 31222
- 83 + 31139 = 31222
- 101 + 31121 = 31222
- 131 + 31091 = 31222
- 239 + 30983 = 31222
Showing the first eight; more decompositions exist.
