Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71528, here are decompositions:
- 109 + 71419 = 71528
- 139 + 71389 = 71528
- 181 + 71347 = 71528
- 199 + 71329 = 71528
- 211 + 71317 = 71528
- 241 + 71287 = 71528
- 271 + 71257 = 71528
- 337 + 71191 = 71528
Showing the first eight; more decompositions exist.
