Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145308, here are decompositions:
- 5 + 145303 = 145308
- 19 + 145289 = 145308
- 41 + 145267 = 145308
- 89 + 145219 = 145308
- 101 + 145207 = 145308
- 131 + 145177 = 145308
- 199 + 145109 = 145308
- 239 + 145069 = 145308
Showing the first eight; more decompositions exist.
