Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145348, here are decompositions:
- 41 + 145307 = 145348
- 59 + 145289 = 145348
- 89 + 145259 = 145348
- 227 + 145121 = 145348
- 239 + 145109 = 145348
- 257 + 145091 = 145348
- 311 + 145037 = 145348
- 317 + 145031 = 145348
Showing the first eight; more decompositions exist.
