Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42318, here are decompositions:
- 11 + 42307 = 42318
- 19 + 42299 = 42318
- 37 + 42281 = 42318
- 61 + 42257 = 42318
- 79 + 42239 = 42318
- 97 + 42221 = 42318
- 109 + 42209 = 42318
- 131 + 42187 = 42318
Showing the first eight; more decompositions exist.
