Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 35728, here are decompositions:
- 131 + 35597 = 35728
- 137 + 35591 = 35728
- 191 + 35537 = 35728
- 197 + 35531 = 35728
- 281 + 35447 = 35728
- 347 + 35381 = 35728
- 389 + 35339 = 35728
- 401 + 35327 = 35728
Showing the first eight; more decompositions exist.
