Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7168, here are decompositions:
- 17 + 7151 = 7168
- 41 + 7127 = 7168
- 47 + 7121 = 7168
- 59 + 7109 = 7168
- 89 + 7079 = 7168
- 149 + 7019 = 7168
- 167 + 7001 = 7168
- 191 + 6977 = 7168
Showing the first eight; more decompositions exist.
