Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42600, here are decompositions:
- 11 + 42589 = 42600
- 23 + 42577 = 42600
- 29 + 42571 = 42600
- 31 + 42569 = 42600
- 43 + 42557 = 42600
- 67 + 42533 = 42600
- 101 + 42499 = 42600
- 109 + 42491 = 42600
Showing the first eight; more decompositions exist.
