Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746400, here are decompositions:
- 31 + 8746369 = 8746400
- 43 + 8746357 = 8746400
- 97 + 8746303 = 8746400
- 139 + 8746261 = 8746400
- 163 + 8746237 = 8746400
- 193 + 8746207 = 8746400
- 283 + 8746117 = 8746400
- 307 + 8746093 = 8746400
Showing the first eight; more decompositions exist.
