Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15272, here are decompositions:
- 3 + 15269 = 15272
- 13 + 15259 = 15272
- 31 + 15241 = 15272
- 73 + 15199 = 15272
- 79 + 15193 = 15272
- 151 + 15121 = 15272
- 181 + 15091 = 15272
- 199 + 15073 = 15272
Showing the first eight; more decompositions exist.
