Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157528, here are decompositions:
- 5 + 157523 = 157528
- 71 + 157457 = 157528
- 101 + 157427 = 157528
- 179 + 157349 = 157528
- 251 + 157277 = 157528
- 257 + 157271 = 157528
- 269 + 157259 = 157528
- 281 + 157247 = 157528
Showing the first eight; more decompositions exist.
