Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12536, here are decompositions:
- 19 + 12517 = 12536
- 79 + 12457 = 12536
- 103 + 12433 = 12536
- 127 + 12409 = 12536
- 157 + 12379 = 12536
- 163 + 12373 = 12536
- 193 + 12343 = 12536
- 283 + 12253 = 12536
Showing the first eight; more decompositions exist.
