Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20492, here are decompositions:
- 13 + 20479 = 20492
- 61 + 20431 = 20492
- 103 + 20389 = 20492
- 139 + 20353 = 20492
- 151 + 20341 = 20492
- 223 + 20269 = 20492
- 331 + 20161 = 20492
- 349 + 20143 = 20492
Showing the first eight; more decompositions exist.
