Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43580, here are decompositions:
- 3 + 43577 = 43580
- 7 + 43573 = 43580
- 37 + 43543 = 43580
- 139 + 43441 = 43580
- 181 + 43399 = 43580
- 373 + 43207 = 43580
- 379 + 43201 = 43580
- 421 + 43159 = 43580
Showing the first eight; more decompositions exist.
