Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42394, here are decompositions:
- 3 + 42391 = 42394
- 71 + 42323 = 42394
- 101 + 42293 = 42394
- 113 + 42281 = 42394
- 137 + 42257 = 42394
- 167 + 42227 = 42394
- 173 + 42221 = 42394
- 197 + 42197 = 42394
Showing the first eight; more decompositions exist.
