Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11492, here are decompositions:
- 3 + 11489 = 11492
- 109 + 11383 = 11492
- 139 + 11353 = 11492
- 163 + 11329 = 11492
- 181 + 11311 = 11492
- 193 + 11299 = 11492
- 241 + 11251 = 11492
- 331 + 11161 = 11492
Showing the first eight; more decompositions exist.
