Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72306, here are decompositions:
- 19 + 72287 = 72306
- 29 + 72277 = 72306
- 37 + 72269 = 72306
- 53 + 72253 = 72306
- 79 + 72227 = 72306
- 83 + 72223 = 72306
- 137 + 72169 = 72306
- 139 + 72167 = 72306
Showing the first eight; more decompositions exist.
