Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 386, here are decompositions:
- 3 + 383 = 386
- 7 + 379 = 386
- 13 + 373 = 386
- 19 + 367 = 386
- 37 + 349 = 386
- 73 + 313 = 386
- 79 + 307 = 386
- 103 + 283 = 386
Showing the first eight; more decompositions exist.
