Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42268, here are decompositions:
- 11 + 42257 = 42268
- 29 + 42239 = 42268
- 41 + 42227 = 42268
- 47 + 42221 = 42268
- 59 + 42209 = 42268
- 71 + 42197 = 42268
- 89 + 42179 = 42268
- 137 + 42131 = 42268
Showing the first eight; more decompositions exist.
