Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42248, here are decompositions:
- 61 + 42187 = 42248
- 67 + 42181 = 42248
- 79 + 42169 = 42248
- 109 + 42139 = 42248
- 229 + 42019 = 42248
- 307 + 41941 = 42248
- 337 + 41911 = 42248
- 397 + 41851 = 42248
Showing the first eight; more decompositions exist.
