Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15394, here are decompositions:
- 3 + 15391 = 15394
- 11 + 15383 = 15394
- 17 + 15377 = 15394
- 107 + 15287 = 15394
- 131 + 15263 = 15394
- 167 + 15227 = 15394
- 233 + 15161 = 15394
- 257 + 15137 = 15394
Showing the first eight; more decompositions exist.
