Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15308, here are decompositions:
- 19 + 15289 = 15308
- 31 + 15277 = 15308
- 37 + 15271 = 15308
- 67 + 15241 = 15308
- 109 + 15199 = 15308
- 277 + 15031 = 15308
- 379 + 14929 = 15308
- 421 + 14887 = 15308
Showing the first eight; more decompositions exist.
