Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28340, here are decompositions:
- 31 + 28309 = 28340
- 43 + 28297 = 28340
- 61 + 28279 = 28340
- 139 + 28201 = 28340
- 157 + 28183 = 28340
- 229 + 28111 = 28340
- 241 + 28099 = 28340
- 271 + 28069 = 28340
Showing the first eight; more decompositions exist.
