Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 338, here are decompositions:
- 7 + 331 = 338
- 31 + 307 = 338
- 61 + 277 = 338
- 67 + 271 = 338
- 97 + 241 = 338
- 109 + 229 = 338
- 127 + 211 = 338
- 139 + 199 = 338
Showing the first eight; more decompositions exist.
