Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115528, here are decompositions:
- 5 + 115523 = 115528
- 29 + 115499 = 115528
- 59 + 115469 = 115528
- 107 + 115421 = 115528
- 167 + 115361 = 115528
- 191 + 115337 = 115528
- 197 + 115331 = 115528
- 227 + 115301 = 115528
Showing the first eight; more decompositions exist.
