Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72358, here are decompositions:
- 5 + 72353 = 72358
- 17 + 72341 = 72358
- 71 + 72287 = 72358
- 89 + 72269 = 72358
- 107 + 72251 = 72358
- 131 + 72227 = 72358
- 137 + 72221 = 72358
- 191 + 72167 = 72358
Showing the first eight; more decompositions exist.
