Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169528, here are decompositions:
- 5 + 169523 = 169528
- 71 + 169457 = 169528
- 101 + 169427 = 169528
- 167 + 169361 = 169528
- 269 + 169259 = 169528
- 311 + 169217 = 169528
- 347 + 169181 = 169528
- 431 + 169097 = 169528
Showing the first eight; more decompositions exist.
