Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42188, here are decompositions:
- 7 + 42181 = 42188
- 19 + 42169 = 42188
- 31 + 42157 = 42188
- 127 + 42061 = 42188
- 229 + 41959 = 42188
- 241 + 41947 = 42188
- 277 + 41911 = 42188
- 337 + 41851 = 42188
Showing the first eight; more decompositions exist.
