Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22420, here are decompositions:
- 11 + 22409 = 22420
- 23 + 22397 = 22420
- 29 + 22391 = 22420
- 53 + 22367 = 22420
- 71 + 22349 = 22420
- 113 + 22307 = 22420
- 137 + 22283 = 22420
- 149 + 22271 = 22420
Showing the first eight; more decompositions exist.
