Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12396, here are decompositions:
- 5 + 12391 = 12396
- 17 + 12379 = 12396
- 19 + 12377 = 12396
- 23 + 12373 = 12396
- 53 + 12343 = 12396
- 67 + 12329 = 12396
- 73 + 12323 = 12396
- 107 + 12289 = 12396
Showing the first eight; more decompositions exist.
