Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19472, here are decompositions:
- 3 + 19469 = 19472
- 31 + 19441 = 19472
- 43 + 19429 = 19472
- 139 + 19333 = 19472
- 163 + 19309 = 19472
- 199 + 19273 = 19472
- 223 + 19249 = 19472
- 241 + 19231 = 19472
Showing the first eight; more decompositions exist.
