Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19436, here are decompositions:
- 3 + 19433 = 19436
- 7 + 19429 = 19436
- 13 + 19423 = 19436
- 19 + 19417 = 19436
- 103 + 19333 = 19436
- 127 + 19309 = 19436
- 163 + 19273 = 19436
- 199 + 19237 = 19436
Showing the first eight; more decompositions exist.
