Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72268, here are decompositions:
- 17 + 72251 = 72268
- 41 + 72227 = 72268
- 47 + 72221 = 72268
- 101 + 72167 = 72268
- 107 + 72161 = 72268
- 167 + 72101 = 72268
- 179 + 72089 = 72268
- 191 + 72077 = 72268
Showing the first eight; more decompositions exist.
