Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72316, here are decompositions:
- 3 + 72313 = 72316
- 29 + 72287 = 72316
- 47 + 72269 = 72316
- 89 + 72227 = 72316
- 149 + 72167 = 72316
- 227 + 72089 = 72316
- 239 + 72077 = 72316
- 263 + 72053 = 72316
Showing the first eight; more decompositions exist.
