Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15222, here are decompositions:
- 5 + 15217 = 15222
- 23 + 15199 = 15222
- 29 + 15193 = 15222
- 61 + 15161 = 15222
- 73 + 15149 = 15222
- 83 + 15139 = 15222
- 101 + 15121 = 15222
- 131 + 15091 = 15222
Showing the first eight; more decompositions exist.
