Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42588, here are decompositions:
- 11 + 42577 = 42588
- 17 + 42571 = 42588
- 19 + 42569 = 42588
- 31 + 42557 = 42588
- 79 + 42509 = 42588
- 89 + 42499 = 42588
- 97 + 42491 = 42588
- 101 + 42487 = 42588
Showing the first eight; more decompositions exist.
