Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15248, here are decompositions:
- 7 + 15241 = 15248
- 31 + 15217 = 15248
- 61 + 15187 = 15248
- 109 + 15139 = 15248
- 127 + 15121 = 15248
- 157 + 15091 = 15248
- 379 + 14869 = 15248
- 397 + 14851 = 15248
Showing the first eight; more decompositions exist.
