Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 378, here are decompositions:
- 5 + 373 = 378
- 11 + 367 = 378
- 19 + 359 = 378
- 29 + 349 = 378
- 31 + 347 = 378
- 41 + 337 = 378
- 47 + 331 = 378
- 61 + 317 = 378
Showing the first eight; more decompositions exist.
