Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7222, here are decompositions:
- 3 + 7219 = 7222
- 11 + 7211 = 7222
- 29 + 7193 = 7222
- 71 + 7151 = 7222
- 101 + 7121 = 7222
- 113 + 7109 = 7222
- 179 + 7043 = 7222
- 239 + 6983 = 7222
Showing the first eight; more decompositions exist.
