Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145432, here are decompositions:
- 41 + 145391 = 145432
- 71 + 145361 = 145432
- 83 + 145349 = 145432
- 149 + 145283 = 145432
- 173 + 145259 = 145432
- 179 + 145253 = 145432
- 239 + 145193 = 145432
- 293 + 145139 = 145432
Showing the first eight; more decompositions exist.
