Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42388, here are decompositions:
- 29 + 42359 = 42388
- 89 + 42299 = 42388
- 107 + 42281 = 42388
- 131 + 42257 = 42388
- 149 + 42239 = 42388
- 167 + 42221 = 42388
- 179 + 42209 = 42388
- 191 + 42197 = 42388
Showing the first eight; more decompositions exist.
