Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15284, here are decompositions:
- 7 + 15277 = 15284
- 13 + 15271 = 15284
- 43 + 15241 = 15284
- 67 + 15217 = 15284
- 97 + 15187 = 15284
- 163 + 15121 = 15284
- 193 + 15091 = 15284
- 211 + 15073 = 15284
Showing the first eight; more decompositions exist.
