Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12272, here are decompositions:
- 3 + 12269 = 12272
- 19 + 12253 = 12272
- 31 + 12241 = 12272
- 61 + 12211 = 12272
- 109 + 12163 = 12272
- 163 + 12109 = 12272
- 199 + 12073 = 12272
- 223 + 12049 = 12272
Showing the first eight; more decompositions exist.
