Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43738, here are decompositions:
- 17 + 43721 = 43738
- 47 + 43691 = 43738
- 89 + 43649 = 43738
- 131 + 43607 = 43738
- 197 + 43541 = 43738
- 239 + 43499 = 43738
- 251 + 43487 = 43738
- 257 + 43481 = 43738
Showing the first eight; more decompositions exist.
