Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145528, here are decompositions:
- 11 + 145517 = 145528
- 17 + 145511 = 145528
- 41 + 145487 = 145528
- 137 + 145391 = 145528
- 167 + 145361 = 145528
- 179 + 145349 = 145528
- 239 + 145289 = 145528
- 269 + 145259 = 145528
Showing the first eight; more decompositions exist.
