Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19430, here are decompositions:
- 3 + 19427 = 19430
- 7 + 19423 = 19430
- 13 + 19417 = 19430
- 43 + 19387 = 19430
- 97 + 19333 = 19430
- 157 + 19273 = 19430
- 163 + 19267 = 19430
- 181 + 19249 = 19430
Showing the first eight; more decompositions exist.
