Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22556, here are decompositions:
- 7 + 22549 = 22556
- 13 + 22543 = 22556
- 73 + 22483 = 22556
- 103 + 22453 = 22556
- 109 + 22447 = 22556
- 277 + 22279 = 22556
- 283 + 22273 = 22556
- 367 + 22189 = 22556
Showing the first eight; more decompositions exist.
