Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19424, here are decompositions:
- 3 + 19421 = 19424
- 7 + 19417 = 19424
- 37 + 19387 = 19424
- 43 + 19381 = 19424
- 151 + 19273 = 19424
- 157 + 19267 = 19424
- 193 + 19231 = 19424
- 211 + 19213 = 19424
Showing the first eight; more decompositions exist.
