Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22138, here are decompositions:
- 5 + 22133 = 22138
- 29 + 22109 = 22138
- 47 + 22091 = 22138
- 59 + 22079 = 22138
- 71 + 22067 = 22138
- 101 + 22037 = 22138
- 107 + 22031 = 22138
- 227 + 21911 = 22138
Showing the first eight; more decompositions exist.
