Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748172, here are decompositions:
- 5 + 8748167 = 8748172
- 11 + 8748161 = 8748172
- 29 + 8748143 = 8748172
- 239 + 8747933 = 8748172
- 269 + 8747903 = 8748172
- 281 + 8747891 = 8748172
- 353 + 8747819 = 8748172
- 383 + 8747789 = 8748172
Showing the first eight; more decompositions exist.
