Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145366, here are decompositions:
- 5 + 145361 = 145366
- 17 + 145349 = 145366
- 59 + 145307 = 145366
- 83 + 145283 = 145366
- 107 + 145259 = 145366
- 113 + 145253 = 145366
- 173 + 145193 = 145366
- 227 + 145139 = 145366
Showing the first eight; more decompositions exist.
