Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72298, here are decompositions:
- 11 + 72287 = 72298
- 29 + 72269 = 72298
- 47 + 72251 = 72298
- 71 + 72227 = 72298
- 131 + 72167 = 72298
- 137 + 72161 = 72298
- 197 + 72101 = 72298
- 251 + 72047 = 72298
Showing the first eight; more decompositions exist.
