Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 392, here are decompositions:
- 3 + 389 = 392
- 13 + 379 = 392
- 19 + 373 = 392
- 43 + 349 = 392
- 61 + 331 = 392
- 79 + 313 = 392
- 109 + 283 = 392
- 151 + 241 = 392
Showing the first eight; more decompositions exist.
