Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12356, here are decompositions:
- 13 + 12343 = 12356
- 67 + 12289 = 12356
- 79 + 12277 = 12356
- 103 + 12253 = 12356
- 193 + 12163 = 12356
- 199 + 12157 = 12356
- 283 + 12073 = 12356
- 307 + 12049 = 12356
Showing the first eight; more decompositions exist.
