Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 366, here are decompositions:
- 7 + 359 = 366
- 13 + 353 = 366
- 17 + 349 = 366
- 19 + 347 = 366
- 29 + 337 = 366
- 53 + 313 = 366
- 59 + 307 = 366
- 73 + 293 = 366
Showing the first eight; more decompositions exist.
