Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72328, here are decompositions:
- 41 + 72287 = 72328
- 59 + 72269 = 72328
- 101 + 72227 = 72328
- 107 + 72221 = 72328
- 167 + 72161 = 72328
- 227 + 72101 = 72328
- 239 + 72089 = 72328
- 251 + 72077 = 72328
Showing the first eight; more decompositions exist.
