Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7288, here are decompositions:
- 5 + 7283 = 7288
- 41 + 7247 = 7288
- 59 + 7229 = 7288
- 101 + 7187 = 7288
- 137 + 7151 = 7288
- 167 + 7121 = 7288
- 179 + 7109 = 7288
- 269 + 7019 = 7288
Showing the first eight; more decompositions exist.
