Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22418, here are decompositions:
- 37 + 22381 = 22418
- 127 + 22291 = 22418
- 139 + 22279 = 22418
- 229 + 22189 = 22418
- 271 + 22147 = 22418
- 307 + 22111 = 22418
- 367 + 22051 = 22418
- 379 + 22039 = 22418
Showing the first eight; more decompositions exist.
