Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22442, here are decompositions:
- 61 + 22381 = 22442
- 73 + 22369 = 22442
- 139 + 22303 = 22442
- 151 + 22291 = 22442
- 163 + 22279 = 22442
- 271 + 22171 = 22442
- 283 + 22159 = 22442
- 313 + 22129 = 22442
Showing the first eight; more decompositions exist.
