Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42580, here are decompositions:
- 3 + 42577 = 42580
- 11 + 42569 = 42580
- 23 + 42557 = 42580
- 47 + 42533 = 42580
- 71 + 42509 = 42580
- 89 + 42491 = 42580
- 107 + 42473 = 42580
- 113 + 42467 = 42580
Showing the first eight; more decompositions exist.
