Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42308, here are decompositions:
- 127 + 42181 = 42308
- 139 + 42169 = 42308
- 151 + 42157 = 42308
- 349 + 41959 = 42308
- 367 + 41941 = 42308
- 397 + 41911 = 42308
- 421 + 41887 = 42308
- 457 + 41851 = 42308
Showing the first eight; more decompositions exist.
