Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 318, here are decompositions:
- 5 + 313 = 318
- 7 + 311 = 318
- 11 + 307 = 318
- 37 + 281 = 318
- 41 + 277 = 318
- 47 + 271 = 318
- 61 + 257 = 318
- 67 + 251 = 318
Showing the first eight; more decompositions exist.
