Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72418, here are decompositions:
- 131 + 72287 = 72418
- 149 + 72269 = 72418
- 167 + 72251 = 72418
- 191 + 72227 = 72418
- 197 + 72221 = 72418
- 251 + 72167 = 72418
- 257 + 72161 = 72418
- 317 + 72101 = 72418
Showing the first eight; more decompositions exist.
