Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23538, here are decompositions:
- 7 + 23531 = 23538
- 29 + 23509 = 23538
- 41 + 23497 = 23538
- 79 + 23459 = 23538
- 107 + 23431 = 23538
- 139 + 23399 = 23538
- 167 + 23371 = 23538
- 181 + 23357 = 23538
Showing the first eight; more decompositions exist.
