Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22378, here are decompositions:
- 11 + 22367 = 22378
- 29 + 22349 = 22378
- 71 + 22307 = 22378
- 101 + 22277 = 22378
- 107 + 22271 = 22378
- 131 + 22247 = 22378
- 149 + 22229 = 22378
- 269 + 22109 = 22378
Showing the first eight; more decompositions exist.
