Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15408, here are decompositions:
- 7 + 15401 = 15408
- 17 + 15391 = 15408
- 31 + 15377 = 15408
- 47 + 15361 = 15408
- 59 + 15349 = 15408
- 79 + 15329 = 15408
- 89 + 15319 = 15408
- 101 + 15307 = 15408
Showing the first eight; more decompositions exist.
