Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12402, here are decompositions:
- 11 + 12391 = 12402
- 23 + 12379 = 12402
- 29 + 12373 = 12402
- 59 + 12343 = 12402
- 73 + 12329 = 12402
- 79 + 12323 = 12402
- 101 + 12301 = 12402
- 113 + 12289 = 12402
Showing the first eight; more decompositions exist.
