Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42306, here are decompositions:
- 7 + 42299 = 42306
- 13 + 42293 = 42306
- 23 + 42283 = 42306
- 67 + 42239 = 42306
- 79 + 42227 = 42306
- 83 + 42223 = 42306
- 97 + 42209 = 42306
- 109 + 42197 = 42306
Showing the first eight; more decompositions exist.
