Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19522, here are decompositions:
- 53 + 19469 = 19522
- 59 + 19463 = 19522
- 89 + 19433 = 19522
- 101 + 19421 = 19522
- 131 + 19391 = 19522
- 149 + 19373 = 19522
- 233 + 19289 = 19522
- 263 + 19259 = 19522
Showing the first eight; more decompositions exist.
