Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13222, here are decompositions:
- 3 + 13219 = 13222
- 5 + 13217 = 13222
- 59 + 13163 = 13222
- 71 + 13151 = 13222
- 101 + 13121 = 13222
- 113 + 13109 = 13222
- 173 + 13049 = 13222
- 179 + 13043 = 13222
Showing the first eight; more decompositions exist.
