Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43538, here are decompositions:
- 97 + 43441 = 43538
- 127 + 43411 = 43538
- 139 + 43399 = 43538
- 277 + 43261 = 43538
- 331 + 43207 = 43538
- 337 + 43201 = 43538
- 349 + 43189 = 43538
- 379 + 43159 = 43538
Showing the first eight; more decompositions exist.
