Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 52390, here are decompositions:
- 3 + 52387 = 52390
- 11 + 52379 = 52390
- 29 + 52361 = 52390
- 89 + 52301 = 52390
- 101 + 52289 = 52390
- 131 + 52259 = 52390
- 137 + 52253 = 52390
- 167 + 52223 = 52390
Showing the first eight; more decompositions exist.
