Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145426, here are decompositions:
- 3 + 145423 = 145426
- 137 + 145289 = 145426
- 167 + 145259 = 145426
- 173 + 145253 = 145426
- 233 + 145193 = 145426
- 293 + 145133 = 145426
- 317 + 145109 = 145426
- 383 + 145043 = 145426
Showing the first eight; more decompositions exist.
