Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 394, here are decompositions:
- 5 + 389 = 394
- 11 + 383 = 394
- 41 + 353 = 394
- 47 + 347 = 394
- 83 + 311 = 394
- 101 + 293 = 394
- 113 + 281 = 394
- 131 + 263 = 394
Showing the first eight; more decompositions exist.
