Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12408, here are decompositions:
- 7 + 12401 = 12408
- 17 + 12391 = 12408
- 29 + 12379 = 12408
- 31 + 12377 = 12408
- 61 + 12347 = 12408
- 79 + 12329 = 12408
- 107 + 12301 = 12408
- 127 + 12281 = 12408
Showing the first eight; more decompositions exist.
