Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28222, here are decompositions:
- 3 + 28219 = 28222
- 11 + 28211 = 28222
- 41 + 28181 = 28222
- 59 + 28163 = 28222
- 71 + 28151 = 28222
- 113 + 28109 = 28222
- 191 + 28031 = 28222
- 239 + 27983 = 28222
Showing the first eight; more decompositions exist.
