Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42562, here are decompositions:
- 5 + 42557 = 42562
- 29 + 42533 = 42562
- 53 + 42509 = 42562
- 71 + 42491 = 42562
- 89 + 42473 = 42562
- 101 + 42461 = 42562
- 239 + 42323 = 42562
- 263 + 42299 = 42562
Showing the first eight; more decompositions exist.
