Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42370, here are decompositions:
- 11 + 42359 = 42370
- 47 + 42323 = 42370
- 71 + 42299 = 42370
- 89 + 42281 = 42370
- 113 + 42257 = 42370
- 131 + 42239 = 42370
- 149 + 42221 = 42370
- 173 + 42197 = 42370
Showing the first eight; more decompositions exist.
