Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11272, here are decompositions:
- 11 + 11261 = 11272
- 29 + 11243 = 11272
- 59 + 11213 = 11272
- 101 + 11171 = 11272
- 113 + 11159 = 11272
- 179 + 11093 = 11272
- 269 + 11003 = 11272
- 293 + 10979 = 11272
Showing the first eight; more decompositions exist.
