Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22380, here are decompositions:
- 11 + 22369 = 22380
- 13 + 22367 = 22380
- 31 + 22349 = 22380
- 37 + 22343 = 22380
- 73 + 22307 = 22380
- 89 + 22291 = 22380
- 97 + 22283 = 22380
- 101 + 22279 = 22380
Showing the first eight; more decompositions exist.
