Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42658, here are decompositions:
- 17 + 42641 = 42658
- 47 + 42611 = 42658
- 89 + 42569 = 42658
- 101 + 42557 = 42658
- 149 + 42509 = 42658
- 167 + 42491 = 42658
- 191 + 42467 = 42658
- 197 + 42461 = 42658
Showing the first eight; more decompositions exist.
