Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19156, here are decompositions:
- 17 + 19139 = 19156
- 83 + 19073 = 19156
- 197 + 18959 = 19156
- 239 + 18917 = 19156
- 257 + 18899 = 19156
- 317 + 18839 = 19156
- 353 + 18803 = 19156
- 359 + 18797 = 19156
Showing the first eight; more decompositions exist.
