Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19222, here are decompositions:
- 3 + 19219 = 19222
- 11 + 19211 = 19222
- 41 + 19181 = 19222
- 59 + 19163 = 19222
- 83 + 19139 = 19222
- 101 + 19121 = 19222
- 149 + 19073 = 19222
- 191 + 19031 = 19222
Showing the first eight; more decompositions exist.
